First that we commit mistake, we are illusioned, we cheat, and at the end, all our senses are imperfect. Just like we are very much proud of seeing. Everyone says: "Can you show me? I want to see." And what you can see? What is the power of seeing? At night, if there is no sunshine, you cannot see, so what is the use of your seeing? If there is wall, you cannot see what is beyond the wall. You are seeing every day the sun, but we are seeing just like a small disc. But actually it is fourteen hundred thousand times bigger than this earth. Similarly, we cannot see which is situated a very long distance. We cannot see even the eyelid, which is actually with the eyes, but we cannot see it. In this way, if you study, every one of your senses you will find imperfect.
So your senses are imperfect, you are cheating, you are illusioned and you commit mistake. How you can give perfect knowledge? Therefore we don't accept any knowledge from an imperfect personality. That is . . . because that is imperfect knowledge, what is the use of that knowledge? Theorizing. No theory. We want to know fact. That is perfect knowledge.
So that perfect knowledge can come from God. And one who distributes that knowledge exactly as God has said, he is perfect. Just like a post peon comes and delivers you, say, one hundred dollars. So he is not delivering that one hundred dollars. Your friend has sent you one hundred dollars, and his business is to hand over that one hundred dollars as it is, without any change, without taking one dollar from it, no, or adding. No addition, no subtraction. His honesty, his perfection, is that he delivers you that hundred dollars which is sent by your friend. That is his honest . . . perfection.
