Prabhupāda: Their knowledge is imperfect. In the Brahma-saṁhitā it is said, goloka-nāmni nija-dhāmni tale ca tasya (Bs. 5.43).
Yaśodānandana: That is why when Caitanya Mahāprabhu came back to Purī, He said, "I have met many Rāmānujas, many Mādhvas, many Buddhists, but I like Rāmānanda Rāya very much because he has this knowledge of Rādhā-Kṛṣṇa."
Acyutānanda: In South India there are very few Rādhā-Kṛṣṇa devotees. And what they have is from some Purāṇas, the marriage of Rādhā and Kṛṣṇa. They perform Rādhā-Kṛṣṇa kalyana, marriage.
Tamāla Kṛṣṇa: Is that bona fide, Prabhupāda?
Prabhupāda: Yes.
