That supreme original Personality of Godhead, Lord Sri Krsna, expanding His plenary portion as Maha-Visnu, the first incarnation, creates this manifested cosmos, but He is unborn. The creation, however, takes place in Him, and the material substance and manifestations are all Himself. He maintains them for some time and absorbs them into Himself again.
