Know that the wayfarer to Allah has, according to his existential growths [nasha'at-i wujudiyah], certain places, each of which has its particular disciplines. The salik will have to know them before he attains to the Salat of the people of knowledge.
The first is the natural growth and the apparent mundane stage, and its place is the earth of nature. The Messenger of Allah (SA) said: "The earth is made for me a place for prostration and a purifier."  The salik's discipline [adab] at this stage is to make his heart understand that his descending from the invisible growth [nash'ah] and the coming down of the soul from its high and lofty place to the lowest earth of nature and his being reduced from "the best stature" [ahsan-i taqwim] to the lowest of the low are for the voluntary journey to Allah and the ascension to the mi'raj of Proximity and reaching the Court of Allah and the Threshold of His Lordship, which is the objective of creation and the final end of the people of Allah. "May Allah have mercy upon one who knows where he has come from, where he is and where he is going." 
The salik must realize that he has come from the house of Allah's munificence [karamat], and is now in the house of worshipping Allah, and will go to the house of Allah's recompense. The gnositc says: "From Allah, in Allah and to Allah." So, the salik must tell himself, and his spirit, that the house of nature is a mosque for worshipping Allah, and that he has been brought to this world for this purpose, as Allah, the Almighty and Glorified, says: "And I have not created the jinn and the ins [mankind] except that they should worship Me."  After realizing that the house of nature is the mosque for worship, and finding himself in seclusion [mu'takif] in it, he is to observe the relevant disciplines and abstain from remembering other than Allah. He is not to leave the mosque of worship, unless there be a need, such as for relieving himself, and then to return, and not to be familiar except with Allah, nor to have any affiliation with others, as these are contrary to the disciplines of cleaving to the door of Allah. In this stage the knower of Allah will have certain moods [halat] which cannot be written down, and as the writer is out of "the innate disposition of humanity" [fitrat-i insaniyat] , indulging in the overflowing darkened sea of nature, void of truth and reality, as well as of all the stations of the saliks and of the gnostics, the best thing for him is not to disgrace himself in the Presence of Allah, the Almighty, and his close friends, but to go past this stage and take his complaint against the evil-commanding soul to the Sacred Threshold of the Lord of Majesty, as perhaps He would extend to him a helping hand out of His general kindness and all-embracing mercy, and thus he would compensate during the rest of his life for what has passed: "Our Lord! We have been unjust to ourselves, and if You forgive us not and have not mercy on us, we shall certainly be of the losers." 
The second stage is the state of the external and internal powers, which are the visible and invisible soldiers of the soul, whose place is the ground (earth = ard) of man's nature, i.e. his structure and body. The salik's discipline in this respect is to inform the inmost of the heart that the ground (ard) of his nature is the mosque of divinity and the place for the prostration of the soldiers of the Beneficent [rahman]. Therefore, the mosque should not be smeared with the filths or Iblis's intrusion, and the divine soldiers should not be put under the influence or Iblis, so that the ground [ard] of the nature is illuminated with the Lord's light, and be freed from the darkness and the impurity of being away from the Court of the Lord. So, let him believe that his visible and invisible powers are in seclusion in the mosque of the body, and he is to treat his body as he treats a mosque, and to look at his powers as being in seclusion in the Court of Allah. In this stage, the obligations of the salik are more, because it is his own responsibility to undertake cleaning and purifying the mosque, as he also is to observe the disciplines of seclusion on the part of those (visible and invisible powers) that are in seclusion in this mosque. The third stage is the salik's cordial invisible growth [nash'ah], whose place is the invisible barzakhian body of the soul, which is created and developed by the soul itself. The salik's discipline, in this instance, is to make himself realize that this stage greatly differs from other ones, and to preserve it is of the salik's important duties, because the heart is the leader of those in seclusion in the Court (of Allah), and with its corruption all of them will corrupt: "If the scholar is corrupt, the world will corrupt".  The heart of a scholar is a small world, while the scholar is the heart of the big world. In this stage the salik's duties increase, because the building of the mosque is also added to his responsibilities, and it maybe that God forbid! -his mosque will be a mosque of harm [dirar], of disbelief and of disunity of the Muslims. In such a mosque it is not allowed to worship Allah, and it must be pulled down. Having established the divine invisible mosque with the hand of the Beneficent and of the guardianship, and purified it from all impurities and Satanic intrusions, and begun his seclusion therein, the salik is to strive to take himself out of his seclusion in the mosque in order to seclude in the Court of the Owner of the mosque. And, after purging himself from self-love and getting out of his own fetters, he himself will become the house of Allah, or better to say, he will become the mosque of the Lord, and Allah will glorify Himself through Manifestation of Action, then of Names and of Essence in that mosque, and this glorification is the salat of the Lord, saying: subbuhun quddus, rabbul mala 'ikati war ruh [All-Glorious, All-Holy, the Lord of the angels and the spirit). 
The traveller to Allah has, in all the stages of the journey, another duty to perform, neglecting which is not permissible at all, for actually it is the core of the cores and the objective of the suluk. This duty is not to forget to remember Allah in any situation or stage, and to seek to know Allah from all rituals and worships, and to see Him in all phenomena, and not to let the blessings and munificence prevent him from the company [suhbat] and privacy, as this is a kind of istidraj (being engaged in other than the Haqq). In short, he is to take the spirit and the interior [batin] of the worships and rituals to be knowing Allah, and to look into them for the Beloved so that the attachment of loving and being loved becomes fixed in his heart, and he may be favoured with hidden graces and secret associations.
It is stated in Misbahush-Shari'ah that Imam as Sadiq (AS) said: "When you arrive at the door of the mosque, know that you have come to the door of a great King. No one may walk into His Courtyard save the purified, and no one is admitted to His Company [mu'anasah] but the truthful. So, attach reverence to your coming to the ground of serving the King, as you would be exposed to a great danger if you were negligent.  Know that He is capable of doing what He likes of justice and grace with you and by you. So, if He was kind to you with His mercy and favour, He would accept from you little worship and give you much reward for it. But if He demanded from you a share of truth and sincerity, to be just with you, He would block you and reject your worship, even if it is much. He is the doer of what He wants. Confess to His Presence your inability, shortcoming, humility and poverty, as you have come to Him to worship and to get His Intimacy [mu'anasah]. Expose your secrets to Him, knowing that nothing, covert and overt, of the entire universe, is hidden from Him. Be, before Him, as the poorest of His servants. Empty your heart of all occupants that keep you away from your Lord, as He does not accept except the pure(st) and the sincere(st). Find out in which register your name is recorded. If you tasted the sweetness of supplication and the delight of addressing Him, and drank from the cup of His mercy and generosity out of His good reception of you and response to you, then you would become suitable for His service. So, enter, as you will have permission and protection. Otherwise, stop, like the one whose rope has snapped, and his hope has come short, and time has got the better of him. So, if Allah found in your heart true recourse to Him, He would look at you with the eye of kindness, mercy and leniency, and cause you to be successful in attaining to what He likes and is pleased with, since He is generous and loves generosity for His servants who distressfully resort to Him and burn out at His door for the want of His pleasure. Allah, the Most High, says: 'Or, Who answers the distressed one, when he calls upon Him, and removes the evil ... ?"
