QUOTE : Mir Dimad (d. 1631) and his pupil Mulla Sadra (d. 1640) founded a school of mystical philosophy at Isfahan, which Majlisi did his best to suppress. They continued the tradition of Suhrawardi, linking philosophy and spirituality, and training their disciples in mystical disciplines which enabled them to acquire a sense of the alam al-mithal and the spiritual world. Both insisted that a philosopher must be as rational and scientific as Aristotle, but that he must also cultivate the imaginative, intuitive approach to truth. Both were utterly opposed to the new intolerance of some of the ulama, which they regarded as a perversion of religion. Truth could not be imposed by force and intellectual conformism was incompatible with true faith. Mulla Sadra also saw political reform as inseparable from spirituality. In his masterpiece Al-Afsan al-Arbaah (The Fourfold Journey), he described the mystical training that a leader must undergo before he could start to transform the mundane world. He must first divest himself of ego, and receive divine illumination and mystical apprehension of God. It was a path that could bring him to the same kind of spiritual insight as the Shii imams, though not, of course, on the same level as they.
