PURPORT
Brahma has confirmed that Lord Krsna is the Supreme, the source of the three manifestations known as Ksirodakasayi Visnu, Garbhodakasayi Visnu and Karanodakasayi Visnu (Maha-Visnu).
For His pastimes, Lord Krsna has four original manifestations-namely Vasudeva, Sankarsana, Pradyumna and Aniruddha.
The first purusa-avatara, Maha-Visnu in the Causal Ocean, who is the creator of the aggregate material energy, is an expansion of Sankarsana; the second purusa, Garbhodakasayi Visnu, is an expansion of Pradyumna; and the third purusa, Ksirodakasayi Visnu, is an expansion of Aniruddha.
All these are within the category of manifestations of Narayana, who is a manifestation of Sri Krsna.
