Ishwara has been described as a magician (Mayavi) in the Upanishads. Ramanuja interprets it as the power of Ishwara for creating the universe is as astonishing as the power of the magician. Maya is that power of Ishwara which creates unusual objects.
In this way, Ramanuja’s description of Parkriti differs from the explanation of Maya put forward by Samakara. This distinction will be clear from the following table:
Prakriti (Ramanuja):
1. Prakriti is real. It is not unreal and indeterminate.
2. The knowledge of Prakriti as the universe is true. No object is unreal. The universe is real.
3. The statements ostensibly denying the reality of the world means only this that there is one Brahman at the root of all multiplicity, not that the world does not exist.
4. Prakriti is the unconscious elements present in Ishwara. It exists in subtle seed form, and it is with this that Ishwara creates the Universe. It is the real or actual product of the unconscious element.
5. The unconscious element existing in God is susceptible to distortion (hence in Ishwara also) and this is real.
6. Prakriti itself appears in the form of its past remaining elements and the entire universe is pervaded by it.
7. According to Parinamavada, Prakriti actually changes into the world.
Maya (Samakara):
1. Maya is indeterminate. It is neither real nor unreal.
2. Knowledge of Maya as the universe is illusory, not real.
3. According to this statement of the Upanishads, multiplicity is unreal.
4. Maya is the power of Ishwara. It does not exist in Ishwara in seed form. It is merely His desire or wish.
5. The power of the creation appears to be prakriti of the world only to those persons who see it as the world and not its fundamental Brahman nature.
6. The universe itself is not Maya. Maya is not transformed or changed, but it is only the magical power of Ishwara, which due to ignorance, reflects Brahman in the form of the universe.
7. According to Vivartavada, Maya is the object of intuition. The universe is the illusion of Brahman.
