Word for word: 
prabhu kahe — the Lord said; pūrve — previously; siddha — perfected; kṛṣṇe — in Kṛṣṇa consciousness; tomāra — your; prīti — love for Kṛṣṇa; tomā-saṅge — by your association; āmā-sabāra — of all of us; haila — there was; kṛṣṇe — unto Kṛṣṇa; mati — consciousness.
Translation: 
Śrī Caitanya Mahāprabhu said to Sārvabhauma Bhaṭṭācārya, “From your previous birth you have been in Kṛṣṇa consciousness. Thus you love Kṛṣṇa so much that simply by your association we are all developing Kṛṣṇa consciousness.”
