Description of Evolution of the Universe - Verse 36

Sūta narrated: Thus willingly these Prakṛtis (evolutes of Prakṛti) are stationed ready in destroying mutually. They stand ready at the time of creation; they sustain, mutually and they devour mutually. Those Vikāras (effects) abide in the Vikārins (causes) by way of the supporter-supported relationship. The Avyakta (the unmaṃfest one) is called Kṣetra and Brahman is called Kṣetrajñia.
