CC Madhya 3.33

ācārya kahe — tumi yāhāṅ, sei vṛndāvana
mora bhāgye gaṅgā-tīre tomāra āgamana
Word for word: 
ācārya kahe — Ācārya replied; tumi yāhāṅ — wherever You are; sei — that; vṛndāvana — Vṛndāvana; mora bhāgye — by My great fortune; gaṅgā-tīre — on the bank of the Ganges; tomāra āgamana — Your appearance.
Translation: 
Advaita Ācārya disclosed the whole situation, telling Śrī Caitanya Mahāprabhu, “Wherever You are, that is Vṛndāvana. Now it is My great fortune that You have come to the bank of the Ganges.”
