Nāmarūpa-vyākaraṇa (Sanskrit: नामरुपव्याकरण), in Hindu philosophy, refers to the process of evolution of differentiation into names and forms i.e. to the unfolding of the primal state into the manifest world prior to which unfolding there was nothing that existed; it refers to the conditioned reality.
According to Hindu scriptures the world in each age emanates from Brahman mirrored upon maya.
[2] The sage of the Chandogya Upanishad regarded the creation of the universe as a huge chest/egg from a Primeval Being existing as the undifferentiated whole, who alone existed without a second prior to the commencement of the process of creation which was the beginning of the differentiation of the undifferentiated.
[3] Adhikarana Saravali of Sri Vedanta Desika (Sloka 9.21-22) explains that the evolution of names and forms is the work of the Universal Self and not of the Individual self.
In Sanskrit, Ishvara is "Mayaopahita-chaitanya"- Pure Consciousness or Brahman in association with Maya.)
