Redefinition of philosophical concepts on the basis of Sadra's doctrine of personal unity of existence

Mulla Sadra has been accused of electing two different conceptual schemes of philosophy and mysticism. However، it can be said that he reconstructed and redefined fundamental philosophical concepts in light of mystical doctrines. In this view، he replaced gradation of being with gradation of manifestations of Being and instauration with theophany and the two part distinction with all-embracing one. Moreover، with a reconsideration of matter and form، he reduced substantial motion in being to substantial motion in manifestations. Thus، the intellectual stage is the manifestation of divine stage and the imaginal stage is the manifestation of intellectual one and finally the material world is the manifestation of imaginal one. In this context، motion which is gradual going out of potentiality to actuality means gradual exodus of exoteric to esoteric thing.
