The original conception of prakrti (material nature) is that it is also conscious and personal. Maya is also conscious, in that, she also has got her personality. There is Brahma-loka and viraja. The viraja side is prakrti. Brahma means brhat - the prakrti as a whole. The ksana is the ray of bija (seed) sent by tal-linga bhagavan sambhuh. The ray is the linga from Maha-Visnu and that enters into viraja.
