CC Madhya 10.150

govindera saṅge kare prabhura sevana
govindera bhāgya-sīmā nā yāya varṇana
Word for word: 
govindera saṅge — with Govinda; kare — do; prabhura — of Śrī Caitanya Mahāprabhu; sevana — service; govindera — of Govinda; bhāgya-sīmā — the limit of good fortune; — not; yāya varṇana — can be described.
Translation: 
They all remained with Govinda to serve Śrī Caitanya Mahāprabhu; therefore no one could estimate the good fortune of Govinda.
