This is a continuous annihilation and recreation. However,in Sadra’s view the annihilation is not a pure and not posterior to recreationeither, rather it is a creation upon creation, to quote himself, it is dressingupon dressing (Sadra and Dehsbashi, 2011). Therefore, Sadra’s ontologylies in the realms of Being, realm of unity, and becoming, realm ofmultiplicity, in the later one motion and time constitute two of itsfundamental dimensions (Kamal, 2006). According to the theory oftrans-substantial motion, changes in the realm of multiplicity occurringgradually in the form and essence. Everything in the sensible world has amomentary existence, precedent for its non-being, whichis, soon or late, transforms to a new level of existence. This perpetualprocess of evolution needs a continuous effusion of Divine essence.
This process of perpetual becoming, volatile and ongoingexistence can be described as a motion towards perfection. The realm ofmultiplicity is the realm of potentiality and imperfection, which needs ahorizontal ascending towards Absolute Being and perfection. Mulla Sadra usesthe Sufi term of love as a driving force behind this gradual movement. This ongoingtransition occurring intertwined with time, as a dimension of existence, thereis no a container outside of existence known as time, it is a part of beings. (Mulla Sadra1999/vol.3: 110-147).
