CC Ādi 10.10

dui śākhāra upaśākhāya tāṅ-sabāra gaṇana
yāṅra gṛhe mahāprabhura sadā saṅkīrtana
Word for word: 
dui śākhāra — of the two branches; upaśākhāya — on the subbranches; tāṅ-sabāra — of all of them; gaṇana — counting; yāṅra gṛhe — in whose house; mahāprabhura — of Lord Caitanya Mahāprabhu; sadā — always; saṅkīrtana — congregational chanting.
Translation: 
There is no counting the subbranches of these two branches. Śrī Caitanya Mahāprabhu held congregational chanting daily at the house of Śrīvāsa Paṇḍita.
