SB 3.8.10

udaplutam visvam idam tadasid
 yan nidrayamilita-drn nyamilayat
ahindra-talpe ’dhisayana ekah
 krta-ksanah svatma-ratau nirihah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
At that time when the three worlds were submerged in water, Garbhodakasayi Visnu was alone, lying on His bedstead, the great snake Ananta, and although He appeared to be in slumber in His own internal potency, free from the action of the external energy, His eyes were not completely closed.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The Lord is eternally enjoying transcendental bliss by His internal potency, whereas the external potency is suspended during the time of the dissolution of the cosmic manifestation.
