Caitanya-caritāmṛta 23.115
tabe sanātana saba siddhānta puchilā bhāgavata-siddhānta gūḍha sakali kahilā
[tabe sanaatana saba siddhaanta puchilaa bhaagavata-siddhaanta goodha sakali kahilaa]
Blended reading (Sanskrit + English inline)
tabe sanātana saba siddhānta puchilā bhāgavata-siddhānta gūḍha sakali kahilā
Thereafter Sanātana Gosvāmī inquired from Śrī Caitanya Mahāprabhu about all the conclusive statements concerning devotional service, and the Lord very vividly explained all the confidential meanings of Śrīmad-Bhāgavatam.
