Bhagavad-gita As It Is Lectures

They say, all these scientists and philosophers, "Perhaps," "It may be." So where is your knowledge? "It may be" and "perhaps." Why you are taking the post of a teacher? "In future we shall understand." And what is this future? Would you accept a post-dated check? "In future I shall discover, and therefore I am scientist." What is this scientist?

Lecture on BG 2.14 -- Germany, June 21, 1974: So this Kṛṣṇa consciousness movement is to know everything perfectly from the supreme authority, Kṛṣṇa. This is the process. Tad vijñānārthaṁ sa gurum eva abhigacchet [MU 1.2.12]. In order to understand subject matter which is beyond our perception, you have to approach such authority who can inform you. Exactly in the same way: to understand who is my father is beyond my perception, beyond my speculation, but if I accept the authoritative statement of my mother, this is perfect knowledge. So there are three kinds of processes to understand or to advance in knowledge. One is direct perception, pratyakṣa. And the other is authority, and the other is śruti. Śruti means by hearing from the Supreme. So our process is śruti. Śruti means we hear from the highest authority. That is our process, and that is very easy. Highest authority, if He is not in default... Ordinary persons, they are in default. They have got imperfection. The first imperfection is: the ordinary man, they commit mistake. Any great man of the world, you have seen, they commit mistake. And they are illusioned. They accept something as reality which is not reality. Just like we accept this body as reality. This is called illusion. But it is not reality. "I am soul." That is reality. So this is called illusion. And then, with this illusory knowledge, imperfect knowledge, we become teacher. That is another cheating. If you have not... They say, all these scientists and philosophers, "Perhaps," "It may be." So where is your knowledge? "It may be" and "perhaps." Why you are taking the post of a teacher? "In future we shall understand." And what is this future? Would you accept a post-dated check? "In future I shall discover, and therefore I am scientist." What is this scientist? And, above all, our imperfectness of senses. Just like we are seeing one another because there is light. If there is no light, then what is the power of my seeing? But these rascals they do not understand that they are always defective, and still, they are writing books of knowledge. What is your knowledge? We must take knowledge from the perfect person.
