Prabhupāda: One Maharastrian brāhmin, he was devotee of Caitanya Mahāprabhu, he said that, "This incident gave us much pain, sir. If You kindly meet this sannyāsī and talk with him about Vedānta-sūtra, that would be a nice thing." In the meantime, one brāhmin came and invited Lord Caitanya that "I have invited all the sannyāsīns of Benares, but I know You do not meet these Māyāvādī sannyāsīs, but still I have come to invite You. If You kindly accept my invitation."
So Caitanya Mahāprabhu saw this opportunity of meeting Prakāśānanda Sarasvatī. He accepted his invitation, and there was a meeting, and there was discussion of Vedānta-sūtra with Prakāśānanda Sarasvatī, and He converted him to be a Vaisnava. That is another incident.
Hayagrīva: How old is this man?
Prabhupāda: Prakāśānanda Sarasvatī? He was also old man. Not less than sixty years old. Yes.
Hayagrīva: And what was his role, again, in the town? What was he . . . he was a Vedāntist?
Prabhupāda: Prakāśānanda Sarasvatī. He was a Māyāvādī sannyāsī. He accepted Caitanya Mahāprabhu's principle and he offered his respect. He touched His feet. And he also joined. But there is no mention that he became officially a Vaiṣṇava, but he accepted the philosophy of Caitanya Mahāprabhu. But Sārvabhauma Bhaṭṭācārya, officially, he became a Vaiṣṇava.
