Hare Krishna!
The first purusa is the Kaaranodakasaayi Visnu. From His skinholes innumerable universes have sprung up. Second is the Garbhodakasaayi Visnu who enters in each and every universe, and third the Ksirodakasaayi Visnu who is the Paramaatma of every material object, organic or inorganic. One who knows these plenary features of the Personality of Godhead knows also Him (Godhead) properly, and thus the knower becomes freed from the material conditions of birth, death, old age and disease, as it is confirmed in Bhagavad-gita. -- SB 1.3.2
