In the reservoir of water first created by the perspiration of Garbhodakasayi Vishnu, the Lord lies on the Sesha plenary expansion of Vishnu, who is described in Srimad-Bhagavatam and in the four Vedas as follows:
sahasra-sirsha purushah sahasrakshah sahasra-pat
sa bhumim visvato vritvatyatishthad dasangulam
The Vishnu form called Ananta-sayana has thousands of hands and legs and thousands of eyes, and He is the active generator of all the incarnations within the material world.
