Srimad Bhagavatam 10.3.7-8:
mumucur munayo devah
sumanamsi mudanvitah
mandam mandam jaladhara
jagarjur anusagaram
nisithe tama-udbhute
jayamane janardane
devakyam deva-rupinyam
visnuh sarva-guha-sayah
avirasid yatha pracyam
disindur iva puskalah
“The demigods and great saintly persons showered flowers in a joyous mood, and clouds gathered in the sky and very mildly thundered, making sounds like those of the ocean’s waves. Then the Supreme Personality of Godhead, Visnu, who is situated in the core of everyone’s heart, appeared from the heart of Devaki in the dense darkness of night, like the full moon rising on the eastern horizon, because Devaki was of the same category as Sri Krsna.”
