We accept Rāmacandra as God. He brought big, big stones and floated over the ocean. Does a stone float over the ocean? Yes, it floats under the order of God. He can . . . He can do it. The law of gravitation will not act there. He can change. You can see. Million tons heavy, this earth, so many hills, and Pacific Ocean, Atlantic Ocean—it is floating in the air just like a swab of cotton. You are explaining "weightlessness," but that's all right. But you float such thing. You can say so many things.
Therefore we should accept knowledge from such person who is beyond these four defects of conditional life. What is that? Illusion, mistake, cheating and imperfectness. So Śrīmad-Bhāgavatam is that proof. As I told you, that 2,500 years ago, or 5,000 years ago Vyāsadeva wrote about Lord Buddha's appearance. Still, there is appearance of Kalki from this time, henceforward, after 400,000's of years Kalki will appear. And his name, his father's name, the place where he will appear, that is mentioned in the Bhāgavata.
That means tri-kāla-jña. Mahā-muni, he is liberated. He is incarnation of God. He knows past, present, future and everything. That knowledge is perfect. One who knows past, present and future perfectly, we should take knowledge from him. That is our Kṛṣṇa consciousness movement, that we don't accept any knowledge from a person who is defective in so many ways. And what is the value of such knowledge?
He is defective. "Physician heal thyself." A physician suffering from fever, and if I go there, "Sir, I am also feverish. Treat," what is the use of such treatment? His brain is already puzzled. What he can treat?
