Translation: 
The conversations between Rāmānanda Rāya and Śrī Caitanya Mahāprabhu contain the most confidential subject matters, touching the conjugal love between Rādhā and Kṛṣṇa in Vṛndāvana [Vrajabhūmi]. Although they talked at great length about these pastimes, they could not reach the limit of discussion.
