Prabhupāda: Guru more mūrkha, guru more mūrkha dekhi, karila śāsana (CC Adi 7.71). "My Guru Mahārāja has chastised Me, considering Me a fool number one." So Caitanya Mahāprabhu said, guru more mūrkha dekhi: "My Guru Mahārāja saw Me a first-class mūrkha, fool. And therefore he has chastised Me." That is the standard of guru and śiṣya. A guru . . . and Cāṇakya Paṇḍita says, lālane bahavo doṣāḥ. "If you pat, there are so many bad things."
Dr. Patel: Pat the dog, it will lick your face.
Prabhupāda: Lālane bahavo doṣās tāḍane bahavo guṇāḥ. "And if you chastise, there are so many good qualities." Tasmāt putraṁ ca śiṣyaṁ ca taḍayet.
Dr. Patel: Na tu lalayet.
Prabhupāda: Na tu lalayet. Therefore either son or disciple, you must always chastise him, not pat him, "Oh, you are very good boy." "You are nothing. You are doing nothing." That is the business of the guru, to find out fault.
Dr. Patel: Don't spare the rod.
Prabhupāda: (chuckles) Although there is no fault, the guru's business is to, "Where is his fault?" That is guru's business. Tasmād taḍayet na tu lalayet.
Dr. Patel: Yesterday you had a very big congregation here? Or all the chairs were kept out?
Prabhupāda: Yes. People were coming. Therefore we have given. Not very big congregation, but many people came.
Dr. Patel: You are doing in the Fourth Adhyāya.
Prabhupāda: Huh?
Dr. Patel: You are doing in the Fourth Adhyāya for that?
Prabhupāda: Fourth Adhyāya. Yes. Bahūni me vyatītāni janmāni tava cārjuna (BG 4.5).
