The phrase heart carries special importance and has been used extensively in the Holy Quran and narrations. But what is meant with this phrase is not the pine-shaped physical heart located in the left side of the chest which support the animal life system by continuously pumping fresh blood into various parts of the body. Because, the Holy Quran relates things to heart which are not comparable with this pine-shaped heart. e.g.:
1. Reasoning and Comprehension
The Holy Quran said:
"Have they not traveled in the land and have they hearts wherewith to feel and ears wherewith to hear."
-the Holy Quran (22:46)
2. Un-comprehending and Reasoning
The Holy Quran said:
"Having hearts wherewith they understand not, and having eyes wherewith they see not."
-the Holy Quran (7:179)
“And their hearts are sealed, so that they apprehend not.”
-the Holy Quran (9:87)
The Holy Quran said:
“These are they into whose hearts He has impressed faith and strengthened them with a spirit from Him."
-the Holy Quran (58:22)
4. Blasphemy and Disbelief
The Holy Quran said:
"And as for those who believe not in the Hereafter there hearts refuse to know, for they are proud."
-the Holy Quran (16:22)
“Such are they whose hearts and ears and eyes God hath sealed. And such are the heedless.” -the Holy Quran (16:108)
The God-Almighty said in the Holy Quran.
"The Hypocrites fear lest a surah should be revealed concerning them, proclaiming what is in their hearts." -the Holy Quran (9: 64)
6. To Receive Guidance
The God-Almighty said:
"And whosoever believeth in God, He guideth his heart. And God is knower of all things." -the Holy Quran (4:11)
And God said:
“Most surely there is a reminder in this for him who has a heart or he gives ear and is a witness.” -the Holy Quran (50: 37)
The God-Almighty said:
"And obey not him whose heart we have made heedless of Our Remembrance, who followeth his own lust." -the Holy Quran (18:28)
8. Certainty and Tranquility
The God-Almighty has said:
"Verily in the remembrance of God do hearts find rest."
-the Holy Quran (13:28)
"He it is who sent down peace of reassurance into the hearts of the believers that they might add faith unto their faith." -the Holy Quran (48:4)
9. Anxiety and Conflict
The God-Almighty has said:
“They alone ask leave of thee who believe not in God and the Last Day, and whose hearts feel doubt, so in their doubt they waver."
-the Holy Quran (9:45)
10. Blessing and Kindness
The God-Almighty has said:
"And places compassion and mercy in the hearts of those who followed him."
-the Holy Quran (57:27)
"He it is who supporteth thee with His Help and with the believers. And (as for the believers) hath attuned their hearts." -the Holy Quran (8: 62-63)
11. Hot-temper and Cruelty
The God-Almighty said:
"If thou hadst been stern and fierce of heart they would have dispersed from round about thee." -the Holy Quran (3:159)
Therefore, heart in the Holy Quran has been assigned the most important privileged position, and various psychic tasks have been related to it, namely: faith, blasphemy, hypocrisy, reasoning, understanding, not understanding, acceptance of truth, unacceptance of truth, guidance, deviation, sin, intention, purification, corruption, benevolence, aggravation, love, invocation, negligence, fear, anger, doubt, conflict, mercy, cruelty, regret, assurance, arrogance, jealousy, rebellion, offense, and other similar acts. Since the pine shaped piece of flesh called heart could not be the origin of these effects, instead these effects are the consequences of human self and spirit. Therefore, it could be said: What is meant with heart is the same "Celestial Jewel" which controls the degree of human-ness within a human being :
The heart possesses such exalted position in the Holy Quran that it is mentioned when the topic of revelation i.e. communication between God and men is discussed. God-Almighty said to Holy Prophet (S):
"Which is the true spirit hath brought down, upon the heart, that thou mayest be (one) of the warners."
-the Holy Quran (26:193-194)
"Say (O Muhammad, to mankind) who is enemy to Gabriel! For he it is who hath revealed (this scripture) to thy heart by God's leave."
-the Holy Quran (2:97)
The heart's position is so eminent that it sees the revealing angel and hears his voice. The God-Almighty has said:
"And He revealed unto His slave (Prophet Muhammad) that which he revealed. The Heart lied not (in seeing the angel) what it saw."
-the Holy Quran (53:10-11)
5.1. Soundness and Sickness of Heart
Our living depends upon spirit and heart because, they are the ones who manage the bodies. All the parts of the body obey their command and all deeds and action initiate from the heart. Therefore, the salvation and cruelty of a person depends upon his hearts condition. It has been inferred from the Holy Quran and narrations that like the human bodies which are healthy and sick at different times, his heart's condition may also follow the same cycle (i.e. some times it is healthy while at other times it is sick).
God-Almighty in Holy Quran said:
"The day when wealth and sons avail not (any man). Save him who bringeth unto God a whole heart " -the Holy Quran (26: 88-89)
"Lo! therein verily is a reminder for him who hath a heart”
-the Holy Quran (50:37)
"And the Garden is brought nign for those who kept from evil, no longer distant. (And it is said): that is that which ye were promised, (it is) for every pertinent and heedful one, who feareth the Beneficent in secret and cometh with a contrite heart."
-the Holy Quran (50: 21-33)
Therefore, the above verses make it explicit that health of a person is related to his heart's condition and his eternal salvation depends upon his return to God-Almighty with a pure and humble heart. On the other side the Holy Quran introduces some examples of hearts which are sick as follows:
"In their hearts is a disease, and God increaseth their disease."
-the Holy Quran (2:10)
"But as for those in whose hearts is disease, it only addeth wickedness to their wickedness."
-the Holy Quran (9:125)
"And when the hypocrites, and those in whose hearts is a disease were saying: God and His Messenger promised us naught but delusion."
-the Holy Quran (33:12)
"And thou seest those in whose heart is a disease race towards them, saying: We fear lest a change offortune befall us."
-the Holy Quran (5: 52)
In these verses the blasphemy, hypocrisy, and friendship with the pagans have been introduced as heart's sicknesses. Similar verses and hundreds of authentic traditions narrated by Holy Prophet (S) and infallible Imams (A) of his Holy Progeny had stated that human heart and soul are susceptible to sickness like human bodies.
God-Almighty the Creator of heart and soul, the Holy Prophet (S), and Infallible Imams (A) who are the specialists of human beings and their hearts had informed us about the sickness of some of the hearts. Why should we ignore this reality? The real human specialists after identifying the symptoms namely: blasphemy, dissension, unacceptance of truth, arrogance, revenge, anger, criticizing, slander, treason, self-conceit, fear, malevolence, defamation, ill-speaking, back-biting, harshness, oppression, felony, misery, avarice, fault-finding, lying, ambitiousness, hypocrisy, deceit, suspicion, cruelty, self-weakness and many other indecent characteristics, have introduced them as the sickness of heart and soul. Therefore, those who leave this world with such contaminated hearts will not be returning to God with a pure and sound heart to be worthy of the verse:
"The day when wealth and sons avail not (any man). Save him who bringeth unto God a whole heart." -the Holy Quran (26: 88-89)
The sicknesses of heart and self could not be considered as small or insignificant rather they are much more dangerous and incurable as compared to bodily diseases. In case of bodily diseases the physical order of the body looses its equilibrium thus, causing pain, discomfort, and inflicting damage upon a specific part of the body. But this is rather limited and in any case these effects cannot go on beyond the physical life span of the inflicted person. However, the sickness of heart and self are accompanied with continuous anguish, torture, and eternal punishment; the pain and punishment which penetrate until the very depths of heart engulfing the soul with eternal flames.
The heart which remained completely ignorant of God’s existence without witnessing His signs by spending a life of disbelief, deviation, and sins in reality is blind and dark, which will be raised on the Day of Judgment with similar condition, and will have no other choice except to be condemned into Hell to live a painful eternal life full of anguish and torture. The God-Almighty in Holy Quran said:
"But he who turneth away from remembrance" of Me, his will be a narrow life, and I shall bring him blind to the assembly on the Day of Resurrection. He will say: 'My Lord! wherefore hast thou gathered me (hither) blind, when I was wont to see?' He will say: 'so (it must be) our revelations come unto thee but thou didst forget them. In like manner thou art forgotten this Day."
-the Holy Quran (20:124-126)
"Have they not traveled in the land, and have they hearts where with to feel and ears wherewith to hear ? For indeed it is not the eyes that grow blind, but it is the hearts, which are within the bosoms, that grow blind."
-the Holy Quran (22:46)
"Whoso is blind in here will be blind in the Hereafter, and yet further from the road."
-the Holy Quran (17:22)
"And he whom God guideth, he is led aright, while, as for him whom He sendeth astray, for them thou wilt find no protecting friends beside Him, and We shall assemble them on the Day of Resurrection on their faces, blind, dumb, and deaf "
-the Holy Quran (17:97)
May be you will find the above, something strange and may ask: How the esoteric eyes will become blind on the Day of Judgment? Do we have eyes and ears other than these apparent bodily eyes and ears? The reply is: Yes! The Creator of human beings and Divine human doctors had informed that human heart and also soul, have their own eyes, ears, and tongue but of their own kind.
Human self is a mysterious existence possessing a special life in his inner essence. Self has his own world in which there is light as well as darkness, there is purity and cleanliness as well as indignation and contamination, and there is seeing and hearing as well as blindness and deafness. But the light and darkness of that special world is not similar to the light and darkness of this world, rather the belief in God-Almighty, Day of Judgment, Prophethood, and the Holy Quran is the illumination for self's world.
The God-Almighty has said:
"Then those who believe in him (Muhammad) honor him, help him, and follow the light which is sent down with him: They are the successful."
-the Holy Quran (7:157)
"Now hath come unto you light from God and a plain scripture."
-the Holy Quran (5:15)
"Is he whose bosom God hath expanded for the surrender (unto Him), so that he followeth a light from His Lord (as he who disbelieveth) ? Then woe unto those whose hearts are hardened against remembrance of God. Such are in plain error."
-the Holy Quran (39: 22)
God-Almighty has informed that Islam, Quran, faith, and Divine obligations are all illumination and their obedience makes the heart enlightened; although, in reality this happens in this same world but its final result is declared in the Next World. Also, He had informed us that blasphemy, hypocrisy, sinning, non-acceptance of truth all are darkness and make the heart dark and contaminated, which would certainly become manifested in the Next World. The Divine Prophets were dispatched by God-Almighty with the mission of leading human beings out of darkness of blasphemy towards the environment of illumination and belief.
The God-Almighty has said:
"We have revealed unto thee (Muhammad) that thereby thou mayst bring forth mankind from darkness unto light."
-the Holy Quran (14:1)
The believers, by means of illumination of faith, self-purification, good moral conducts, God's-Remembrance, and righteous deeds make their heart and souls illuminated; witness the sublime realities through their esoteric eyes and ears; and ascend toward God's Nearness through various stages of perfection. Such souls when leaving this world will turn into absolute illumination, joy, cheerfulness, beauty, and in the Next World will be utilizing the same illumination accumulated by them in this material world. The God-Almighty has said:
"On the day when thou (Muhammad) wilt see the believers, men and women, their light shining forth before them and on their right hands (and will hear it said unto them): Glad news for you this day: Gardens underneath which rivers flow, wherein ye are immortal. That is the supreme triumph."
-the Holy Quran (57:12)
Yes! The illumination for the eternal world must be arranged in this world, and it is because of this reason that the pagans and hypocrites do not have illumination in the Next World. The God-Almighty has said:
"On the Day when the hypocritical men and the hypocritical women will say unto those who believe, look on us that we may borrow from your light! It will be said: Go back and seek for light!"
-the Holy Quran (57:13)
5.2. Heart in Traditions
The pioneers of religion and real human specialists have left many interesting narrations about the heart. Following are some of the examples: In some of the narrations the hearts have been classified into three categories:
Imam al-Baqir (A) said:
"There are three kinds of hearts:
a: First type: Reversed heart which lacks feelings for any sort of righteous deeds. Such heart is the heart of a unbeliever.
b. Second Type: The heart which contains a black spot in which a war is being waged between the truth and falsehood, and whichever becomes victorious will take over the heart's control.
c. Third type: The conquered heart in which there is a lighted lamp which is never going to be turned off. Such a heart is the heart of a believer."
-Bihar al-Anwar, vol. 70, p-51.
Imam al-Sadiq (A) has quoted from his learned father:
"There is nothing worst than sinning for the heart. When the heart is encountered with sin, it struggles against the sin until sin becomes victorious thus, making the heart as a reversed heart."
-Bihar al-Anwar, vol. 70, p-54.
Imam al-Sajjad (A) has said:
"A man possesses four eyes, with two apparent eyes he sees the affairs relevant to his world, and with two esoteric eyes sees the affairs related to the Next World. Therefore, whenever God-Almighty desired the good for a believer, He opens his heart's eyes to enable him to witness the hidden world and its mysteries. But when He does not desire his welfare, leaves the heart with his esoteric eyes closed."
-Bihar al-Anwar, vol. 70, p-53.
Imam al-Sadiq (A) has said:
"The heart possesses two ears, the spirit of belief slowly invites him towards righteous deeds, while the Satan slowly invites him towards evil deeds. Therefore, whoever becomes victorious in this struggle takes over heart's control.”
-Bihar al-Anwar vol. 70, p-53.
Imam al-Sadiq (A) quotes from the Holy Prophet (S)
"The darkness of the heart is the worst kind of darkness.”
-Bihar al-Anwar, vol. 70, p-51.
Imam al-Baqir (A) said:
"Initially there is a white spot and light within the heart of a human being and as a result of his committing sin, a block spot appears. If the person repents the black spot gets wiped out, but if he persisted in sinning, the blackness gradually increases ultimately covering the entire white spot, When this happens the owner of such heart will never return towards goodness and become manifestation of the Quranic verse:
‘Nay, but that which they have earned is rust upon their hearts.’"
-al-Kafi, vol, 2, p-273.
The Commander of the Faithful Imam" Ali (A) has said:
"Every one who lacks self restraint and piety will have a dead heart; whoever have a dead heart will enter inside the Hell."
-Nahjul Balagha, saying 324
He further emphasized this matter in his last will addressing to his son:
“Oh my son! The poverty is one of the most horrible calamity,. But still severe than poverty is the bodily sickness; and the sickness of soul is harsher than the bodily sickness. Plenty of wealth is one of the God's blessing, but sound health is better than that, and the piety of heart is even superior than sound health."
-Bihar al-Anwar, vol. 70, p-51.
There is a narration quoted from Anas bin Malik from the Holy Prophet (S) who said:
"The prophet David (A) asked God; ‘Oh God! All the emperors possess treasure then where is Your treasure ? God-Almighty replied: ‘I possess a treasure which is greater than the sky; vaster than the Heaven's firmaments; smells better than the perfumes of Paradise, and is beautiful than the Celestial Kingdom. Its earth is enlightenment; its sky is belief, its sun is enthusiasm; its moon is love,. its stars are inspiration and attention towards Me; its clouds are reason,. its rain is blessing, its fruits are obedience; and its yield is wisdom. My Treasure has four doors, the first one is the door of knowledge, the second one is the door of reason, the third one is the door of patience, and the fourth one is the door of contentment. Know that My Treasure is -the heart of a believer' ".
-Bihar al-Anwar, vol. 70, p-59.
The Divine Heart Specialists have described many interesting topics in these traditions. They have divided the hearts into following three categories:
5.2.1. The Heart of an Unbeliever
These Divine Specialists have described that the heart of an infidel is a reversed or over-turned heart which does not contain any goodness in it. Such heart' is deviated from its primordial nature; does not look towards the Upper-Heavens and keeps itself amused and preoccupied into worldly affairs, therefore, it does not witness the existence of God-Almighty and I. Eternal-World. It lacks the proper imagination for goodness and righteous deeds, because, the righteous deeds reach the perfection stage and Gods-Nearness only in cases when they are performed with the intention of attaining His pleasure. But since an infidel has reversed his heart, he does not see God-Almighty any more, and therefore, does not have any other aim except this world in all his affairs.
Such an heart in his primordial nature was blessed with esoteric eyes which now have been blinded because, he cannot witness the most explicit shinning realities i.e. the Creator of the Universe. He is blind and will be raised as blind in the Next World too. In this world he is attached to worldly affairs, and will be raised in the Next World possessed with the same attachment, but since the Eternal-World lacks these worldly amusements, he will burn with the fire of separation. In such heart the light of faith has been extinguished and therefore, it is totally filled with absolute darkness.
5.2.2. The Heart of a Believer
Just opposite to the heart of an unbeliever is the heart of a perfect righteous believers; whose doors are open towards the Upper-Heaven and Unseen-World; is illuminated with the light of faith which will never be turned off; and through its two esoteric eyes witnesses the mysteries of the Hidden-World. Such a heart continuously strives for achieving absolute t perfection, beauty and salvation and seeks God's Pleasure and Blessing. Since he wants God-Almighty therefore, continuously strives to move in His Direction by means of good moral conduct and righteous deeds. Such heart is wider than the Celestial Sky and Divine Thrown, beautiful than the Paradise, is the Divine Treasure and center of manifestation of Heavenly Light; his earth is enlightenment, his sky is faith; his sun is enthusiasm for God's countenance; his moon is God's love; where the wisdom rules and absorbs the rain of Divine Blessings for producing the fruits of worship and obedience; is filled with absolute light, joy, cheerfulness, purity, and will be raised in the next world in the similar state.
5.2.3. The Heart of a Believer- Occasionally Contaminated
The heart of a believer which occasionally gets contaminated with sin is not dark and confined rather is illuminated with the light of faith and remained open for receiving guidance and Divine Blessings. But as a result of sinning it has developed a black spot and Satan has succeeded to make an entry into it. Although, the esoteric eyes are not quite yet blinded but because of sinning have caught a disease which might render them blind. Both angels as well as Satan have access within such heart. The angels enter through the doors of faith and invite him towards goodness while the Satan influences through the black spot inviting him towards evil.
In such a heart both Satan and angel are engaged in a continuous confrontation. Angle wants to take over the control of entire heart forcing Satan out through good deeds on the other side Satan through seduction and sins makes the darker heart further darkest and strives to take over the control of entire heart by forcing out the angel and permanently closing the gateway of belief forever. These two are permanently engaged in a continuous war until one of them become victorious over his opponent, and what is the magnitude of victory achieved. The esoteric life and eternal destination of human being depends upon this struggle. It is here that the struggle with the self becomes of crucial importance, which will be discussed later on in the book.
In his initial primordial nature the heart is bestowed upon with special virtues such as purity, enlightenment, kindness, and blessing. He is sensitive towards other people's difficulties and feels un-comfortable while seeing others in pain even animals. He desires that others should live a pleasant and comfortable life and takes pleasure in doing favors towards them. In accordance with his pure nature is inclined and pays attention towards God-Almighty; takes pleasure in performing worship, prayer, supplication, and other righteous deeds, while immediately feels ashamed and offer repentance if commits sins.
In case the heart accepted invitation of his pure primordial nature and acted accordingly, he becomes purest, kindest, sincerest, and enlightened, because of the effects of worship and prayers his enthusiasm and love for these things increases day by day. But if he neglects and acts against his inner natural feelings and sentiments, they gradually get subdued and eventually become completely silenced and eventually annihilated.
If after seeing the horrible tragic scenes involving others does not show any reaction, gradually becomes used to such things to the extent that further repetition of such encounters will produce least reaction. Also, it is possible that one may reach to a point where seeing the poverty, hunger, and wretchedness involving others not only produce any disturbance with in his conscience on the contrary while seeing the painful scenes of imprisonment, torture, and murders feels happy and pleased. 
If someone commits a sin for the first time, he feels guilty and ashamed about it, but having committed a sin for the first time, to repeat it for the second and third time relatively becomes easier for him, and in case of his persistence in sinning reaches to a point, where not only he does not feel any sense of guilt and shame, on the contrary considers himself victorious and feels happy.
The heart of such persons has become dark and reversed and in the words of the Holy Quran and narrations has acquired hard-heartedness. Satan has occupied these hearts forcing the God's Angels out, and the doors of salvation have been closed permanently leaving no hope for repentance and return towards God-Almighty.
The God-Almighty said in the Holy Quran:
"If only, when our disaster came on them, they had been humble! But their hearts were hardened and the devil made all that they used to do seem fair unto them!"
-the Holy Quran (6:43)
"Then woe unto those whose hearts are hardened against remembrance of God. Such are in plain error.”
-the Holy Quran (39:22)
Imam aI-Baqir (A) said:
"There is a white spot inside the heart of each believer. Once he commits a sin or repeats it, a black spot appears inside the heart. In case of persistence of sins, the black spot, increases, gradually in size filling the entire heart with blackness. When this happens the owner of such heart never returns towards goodness, and this, is what God meant in the verse:
"Nay, but that which they have earned is rust upon their hearts."
-Bihar al-Anwar, vol. 73, p-361.
The Commander of the Faithful Imam' Ali (A) said:
"The tears of eye never get dried but for the sake of hardheartedness,. the heart never acquires hard-heartedness but for the sake of excess of sins."
-Bihar al-Anwar, vol. 73, p-354.
The Holy Prophet (S) said:
"The following four things are the indicators of human cruelty:
1) Dryness of eyes (ii) Hard-heartedness (iii) Excessive greed for earning a living (iv) And persistence of sins.
-Bihar al-Anwar, vol. 73, p-349.
It was because of this reason that the Infallible Imams (A) of prophet's progeny in their supplications took shelter in God-Almighty against hard-heartedness.
Imam al-Sajjad (A) said:
"Oh God! I do complain to you against hard-heartedness –the heart which by means of whims and passions is in the state of continuous revolution and has become contaminated. And I do complain to you against the dryness of eye which does not cry and is not afraid of you, and instead takes pleasure in looking towards whatever makes it pleased."
--Bihar al-Anwar, vol. 94, p-143.
Therefore, a human being who desires his own prosperity and soundness of heart must prevent himself from committing any sin however small it might seems; should gradually motivate his self for performing righteous deeds namely: worship, prayer, communications with God, sincerity, kindness and help towards others, defense of oppressed and deprived, benevolence, and cooperation for achieving social welfare and social justice, so that it performs them as a matter of habit. His inner purity and illumination continues striving for perfection and purification fill his heart becomes a special center of God's favorite angels.
5.4. Heart's Physicians
It has already been explained earlier that like human bodies, hearts could also be healthy and sick, and the eternal prosperity or salvation of a person depends upon his returning to the Next World with a pure and sound heart. It is therefore, important for us to be knowledgeable about the health and sickness of the heart; must identify the symptoms of the disease; and should understand the causes and factors in order to implement all the health care hygienic measures to prevent its spread.
Do we possess self-sufficiency in this matter or do we need the prophets? There is absolutely no doubt that we lack sufficient knowledge about the special creation of human-self and the secrets and mysteries which have been incorporated by the Creator in this Celestial existence. In fact we are ignorant about our psychological and esoteric life; do not well recognize the factors and causes responsible for the self's sickness; cannot properly diagnose the symptoms of the disease; and are not well aware about various kinds of diseases, preventive measures required against their spread, and the available methods of their treatment. Therefore, the presence of Divine Prophets is really required in order to provide guidance and lead us in solving the above mentioned problems.
The prophets are the real physicians and specialists of the souls, who through Divine Blessing and revelations understands very well about the pain as well as the treatment of self. They have been educated and trained in various disciplines dealing with human beings and their souls in the school of revelation, and are thoroughly knowledgeable about the secret and mysteries of this special celestial existence. They understand the straight path of guidance and ascend towards the God-Almighty as well as the causes and factors of deviations, and therefore, are in a position to help lead the human beings in following the straight path and can prevent their deviations.
Yes! the prophets are God's physicians who have rendered most valuable services for humanity throughout the history, which are relatively more valuable than the services rendered by physicians of the human bodies. The prophets were able to discover the mysterious abstract (i.e. Celestial Spirit) for themselves, and by introducing this "Celestial Jewel" to human beings succeeded in reviving their human personality. They were the ones who introduced and enlightened human beings with learning, spirituality, and moral ethics by showing them the path of journey leading towards God's Nearness.
They are the ones who made the humanity familiar with the unseen world and strived for self-purification, self-nourishment and self-refinement of human beings. If there are marks of meaningness, sentiments, love, moral ethics, and other virtues found among human beings it is all due to the blessing of painstaking continuous efforts and endeavors of all God's physicians and specially the Last Divine Messenger Prophet Muhammad (S). If the Divine Prophets would not have been dispatched for human-guidance, certainly the conditions of human beings would have been something different. Yes! The prophets are real distinguished personalities of the humanity, and because of this distinction have been called as physicians of self in the traditions.
The Commander of the Faithful Imam 'Ali (A) said about the Holy Prophet (S).
"Muhammad (S) was a traveling physician who continuously endeavored for the treatment of souls. He had prepared ready-made ointments and arranged other tools of surgery for the treatment of wounds and disinfecting the diseases at suitable occasions. He cured the heart's blindness, ear's deafness, tongue's dumbness, and prescribed medicine for all those who were living in the state of confusion and wandering because, they did not utilized the light of wisdom for abstraction of realities and thus, were forced to live like grazing animals."
-Nahjul Balagha, sermon,108.
The Holy Quran has been described as a health-giving medicine for the diseased hearts.
God-Almighty has said:
"There hath come unto you an exhortation from your Lord. A balm for that which is in the breasts."
-the Holy Quran (10-57)
"And We reveal of the Quran that which is a healing and a mercy for believers."
-the Holy Quran (17:82)
The Commander of the Faithful Imam 'Ali (A) said about the Holy Quran:
"Learn the Holy Quran because, it is the best of learning; pay attentions towards its verses because they are like the springs rain; its recital revives the heart; and utilize the Quranic illumination for the healing of your hearts."
-Nahjul al-Balagha, sermon-110.
At some other place he said:
"Know that anyone who possesses the Holy Quran would not require any thing else, and whoever is deprived of it will never be free from want. By means of the Holy Quran heal the sickness of your hearts and strengthen yourself through it while confronting hardships. Because, it contains the cure for the most severe diseases namely: blasphemy, hypocrisy , and deviations."
-Nahjul al-Balagha, sermon-176.
Yes! the Prophet of Islam is the best physician of the souls. He recognized well our pain and its treatment; brought the Holy Quran and presented it to us which the best program of healing for our internal pains. Apart from that various kind of psychic disease and their treatments have been explained for us through the Holy Prophet (S) and Infallible Imams (A) of his Holy progeny Ahlul Bayt which have been preserved for us in the form of traditions.
Therefore, if we are interested in the happiness and soundness of our self, we must practice the hygienic measures for the psychic and physical health of our self. We must identify these diseases within our souls through Quranic verses and guidelines issued by the Holy Prophet (S) and Infallible Imams (A) and must seriously strive for their treatments. Any negligence shown in this important and crucial task would result in serious damage inflicted upon ourselves, which will become manifested in the Next World.
5.5. Refinement and Perfection of Self
It was already discussed that the self-building and self-nourishment are the most important crucial tasks, because, the happiness and prosperity of both worlds depends upon them. All of the God's Prophets were dispatched for accomplishment of this aim. Self-building must be undertaken into two stages:
Both the above mentioned stages are necessary for achieving self-building, because, unless and until the heart's ground is not thoroughly cleansed from evilness, it would not be available for acquiring higher learning, attaining moral excellence, and performance of righteous deeds. A heart which is contaminated with Satan's presence, how could become a center for the manifestation of Divine Light? How can God's intimate angels enter into such a heart? On the other hand if faith, enlightenment, moral excellence, and righteous deeds do not exist, through, which means the human self will attain nourishment and perfection?
Therefore, for self building both these stages must be attempted simultaneously. On one side the heart must be thoroughly cleansed and purified from all sort of impurities and falsies, and on the other side it should be encouraged and motivated for performance of righteous and virtuous deeds. Satan must be forced out and God's Intimate Angel should be welcomed. Any sort of foreign material other than God's should be thrown out from it, and God's Blessing and Illumination must be absorbed. These two stages are complimentary to each other.
It is not possible to purify the heart and let postpone the performance of righteous deeds for a later opportunity, and likewise we can not ignore the heart's internal impurities and evilness before undertaking the performance of righteous deeds. Therefore, it is necessary that both of these stages must be coordinated, and should be undertaken simultaneously. Avoiding sins and shameful moral deeds invites human being towards goodness, and similarly performance of righteous and virtuous deeds result in his acquittal of sins and obscene deeds. But in order to continue detailed discussion for the both stages it would be better to divide them into separate chapter. Firstly the stage of self-refinement will be discussed.
 The video tapes commercially produced by the Serb criminals showing the most horrible brute crime scenes of mass killings, torture, and raping in recent ethnic cleansing in Bosnia-Herzegovina under the very nose of the United Nations, in the heart-land of civilized Europe, and their welcome by the sadists in the Western countries proves the authenticity of this statement [Tr].
