Srimad Bhagavatam Canto 10, Chapter 13, Text 55

SB 10.13.55

evam sakrd dadarsajah
para-brahmatmano ’khilan
yasya bhasa sarvam idam
vibhati sa-caracaram
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Thus Lord Brahma saw the Supreme Brahman, by whose energy this entire universe, with its moving and nonmoving living beings, is manifested. He also saw at the same time all the calves and boys as the Lord’s expansions.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
By this incident, Lord Brahma was able to see how Krsna maintains the entire universe in different ways. It is because Krsna manifests everything that everything is visible.
