Guest (1): What is the distinction between higher and lower?
Prabhupāda: You do not know? A child is thinking.
Guest (1): No, let us think of what is the highest thing.
Prabhupāda: That you have to learn from the highest man. Yes. That is Bhagavad-gītā. Just like Bhagavad-gītā says that tad viddhi: "You understand that transcendental knowledge by surrender." So if you do not surrender, there is no possibility.
