PURPORT

In the Mahabharata, Santi-parva, it is said that He who is Pradyumna is also Aniruddha. He is also the father of Brahma. Thus Garbhodakasayi Visnu and Ksirodakasayi Visnu are identical plenary expansions of Pradyumna, the original Deity of Brahma, who is born from the lotus flower. It is Pradyumna who gives Brahma direction for cosmic management. A full description of Brahma's birth is given in Srimad-Bhagavatam (3.8.15-16).

Describing the features of the three purusas, the Laghu-bhagavatamrta says that Garbhodakasayi Visnu has a four-handed form, and when He Himself enters the hollow of the universe and lies down in the ocean of milk He is known as Ksirodakasayi Visnu, who is the Supersoul of all living entities, including the demigods. In the Satvata Tantra it is said that the third purusa incarnation, Ksirodakasayi Visnu, is situated as the Supersoul in everyone's heart. This Ksirodakasayi Visnu is an expansion of Garbhodakasayi Visnu for pastimes.
