"You are the ultimate shelter of these three plenary portions. Thus there is not the slightest doubt that You are the primeval Narayana.
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.
