Prabhupāda: The principle is same, that when they grow up they learn the śāstra. The more they read, the more they learn. Then they become preacher, teacher. The grown-up children, those who are fifteen, sixteen, they can teach five-, six-years-old.
Jyotirmāyī: Then they can take responsibility themselves.
Prabhupāda: In this way. Elderly student... That is the way of Indian teaching, that there is one teacher, and how he's managing hundreds? That means there are groups. One who is elderly student, he's taking some beginners: "Write a or A like this." That he can teach. What he has learned, he can teach. Similarly, next group, next group. So in this way, one teacher can manage hundreds of students of different categories. This is organization. Not that everything I have to do. I cannot teach anybody to do it. That is not intelligence. Intelligence is that employ others to help you. That is intelligence. Not that "Oh, I was busy, I could not do it." Why? What about your assistant? Train assistant so that in your absence things can be done. So the elderly students, they could be... Just Caitanya Mahāprabhu used to do that. When He was sixteen years old he could argue with Keśava Kāśmīrī, because He was practiced. In this way, stage after stage, everyone should be expert. Everyone should be teacher and student.
