CC Antya 18.13

sahasra-vadane yabe kahaye ‘ananta’
eka-dinera līlāra tabu nāhi pāya anta
Word for word: 
sahasra-vadane — in thousands of mouths; yabe — when; kahaye — says; ananta — Lord Ananta; eka-dinera — of one day; līlāra — of pastimes; tabu — still; nāhi — does not; pāya — reach; anta — the limit.
Translation: 
If Ananta, with His one thousand hoods, tried to describe even one day’s pastimes of Śrī Caitanya Mahāprabhu, He would find them impossible to describe fully.
