Srimad Bhagavatam Canto 10, Chapter 68, Text 46

SB 10.68.46

tvam eva murdhnidam ananta lilaya
 bhu-mandalam bibharsi sahasra-murdhan
ante ca yah svatma-niruddha-visvah
 sese ’dvitiyah parisisyamanah
 
Translation: 
 
O unlimited one of a thousand heads, as Your pastime You carry this earthly globe upon one of Your heads. At the time of annihilation You withdraw the entire universe within Your body and, remaining all alone, lie down to rest.
