One of the problems with conceit with which one is afflicted as a result of this psychological disease, and as a result of one believing in his own superiority over others and the status which he has with Allāh, he regards others as ignorant, seeing no value for their viewpoint. As a result for this condition, he accepts neither advice from any adviser nor any admonishment from any preacher. One who is deprived of the abundant benefits of admonishment, both the nafs and Satan have a free hand in tempting him.
There is a great deal of emphasis in traditions, statements of great men, poets and wise men, on the company of the folks of righteousness and on being in contact with scholars, so much so that even looking at the face of a scholar is adoration, and looking at his house door is adoration, according to traditions. On one hand, the nafs and Satan find no room to tempt him because, as a result of keeping the scholars and the wise company, he becomes keenly aware of his faults, seeing himself as being derelict on the path towards Allāh.
But if he stops keeping them company, he will be surrounded with detriments, and he becomes unaware of his faults, so he stops seeking his pursuit, claiming he has already achieved his pursuit and no longer needs to exert any effort. One whose condition is like that is definitely going to perish and will imminently fall.
Imām al-Khomeini, may his blessings endure, says that among the harms of conceit is that one looks askance at Allāh's servants, seeing their good deeds as nothing even if they may be better than his own; this, too, is one of the paths towards the annihilation of man and thorns on his path.
