We are born without any perfect knowledge. That is natural. But we have to be taught. We have to sent . . . we have to be sent to school for learning. Therefore these books are there. What for these books are being written? Just for the learning of the human society, so they can learn it. Cats and dogs cannot read this Bhāgavata or Bhagavad-gītā. It is meant for human society. So they should take advantage of this knowledge. But if they remain in the darkness of ignorance, then what is the meaning of their advancement? It has no meaning. So that is going on. They too do not accept knowledge from the authority. They manufacture. How you can manufacture? You are a fool, so whatever you'll manufacture, so-called knowledge, that is also foolish. How can we depend on your foolish knowledge? Abodha-jāta. Everyone is fool. So he cannot manufacture. He has to learn. He has to take knowledge from a person who knows. Then he's perfect.
That is our system. We are taking knowledge from Kṛṣṇa. We are taking knowledge from Bhāgavatam. Therefore our knowledge is perfect. We are taking authority. As we are, we are defective. Our position is sometimes we do mistake—"Two plus two equal to five." But it is not fact. So two plus two must be four. But if we make "five" or "three," that means the whole background becomes wrong. That is . . . we are liable to do that mistake. And illusion. Illusion means two plus two equal to four, I have written "five," but I am seeing it is all right. That is illusion.
