'caitanya-dāsa' nāma śuni' kahe gaura-rāya
'kibā nāma dharāñācha, bujhana nā yāya'
caitanya-dāsa—Caitanya dāsa; nāma—name; śuni'-hearing; kahe gaura-rāya—Śrī Caitanya Mahāprabhu said; kibā—what; nāma—name; dharāñācha—you have given; bujhana nā yāya—it cannot be understood.
When the Lord heard that his name was Caitanya dāsa, He said, "What kind of name have you given him? It is very difficult to understand."
