Not satisfied simply with formal learning...
Not satisfied simply with formal learning, Mulla Sadra left the worldly life in general and retired to a small village named Kahak near Qum where he spent 15 years in asceticism and purification of his soul until, as he claims in his introduction to the Asfar , he became endowed with the direct vision of the intelligible world. He now came to “see” through illumination (ishraq) what he had previously learned theoretically from books.
Having reached both formal and spiritual perfection, Mulla Sadra returned once again to the world. Meanwhile, Allahwirdi Khan, the Governor of Shiraz, had built a large madrasah and invited Mulla Sadra to return to Shiraz as the head of the new school.
Akhund accepted the offer and returned to his native city, making the school of Khan the major centre of intellectual sciences in Persia.[^6] He remained there until the end of his life spending the last period of his terrestrial existence entirely in teaching and writing.
Despite his extreme piety which is shown by the fact that he made the pilgrimage to Mecca seven times on foot – he died in Basrah in 1050/1640 during the seventh journey – Mulla Sadra was often molested by some of the exoteric ‘ulama’ who could not accept his gnostic interpretation of the doctrines of the faith and who denounced him publicly on more than one occasion. It was only the influence of his powerful family that made it possible for him to continue his teaching activities.
Mulla Sadra’s life, then, can be divided into three distinct periods: the period of childhood and schooling in Shiraz and Ispahan, the period of asceticism near Qum at the end of which the composition of the Asfar was begun, and the period of teaching and writing which represents the result and fruition of the other two periods.
His life is itself the testimony of one of the main aspects of his wisdom, that in order to be effective theoretical knowledge must be combined with spiritual realization. The writings of Mulla Sadra, nearly all of which were composed in the last period of his life, are almost without exception of great merit and have been among the main sources from which the later generations of theologians, philosophers, and gnostics have drawn their inspiration.
All his writings concern religious sciences or metaphysics, theodicy or Hikmat ,[^7] and are in a very clear and fluent style making them more easily understandable to the reader than the writings of his predecessors like Mir.
