Then another thing is cheating. So many rascal philosophers and scientists, they have no knowledge, accurate knowledge, but they are writing books. This is cheating. If you do not know what is what, why you are misleading others by writing books? No. He is making money. So cheating. Cheating, illusion, committing mistake. Three. And fourth: that the senses imperfect. They are gathering knowledge through senses. I see... I want to see personally. "All right, put up the light. Now see." That is your seeing power. You see under condition. Therefore your seeing power is imperfect. Your thinking power is imperfect.
So every sense... We are gathering knowledge by the imperfect senses. We are seeing every day, morning, the sun which is bigger than this earth by fourteen hundred thousand times. And we are seeing just like a plate. If he's not informed by an authority when he goes to school... The teacher of geography, when he informs, "My dear boy, the sun is very, very big," then he can understand. I am seeing that the one airplane is running very fast, flying in the sky. A child sees, "Oh, such a big thing. How it is flying?" He does not know that this machine is not flying independently. There is a pilot. Without this pilot all this mechanical arrangement is simply void. If that airplane is kept down for many thousands of years with all the machine complete, it has no power to fly unless there is the expert pilot who pushes on the button, it will fly. So therefore imperfect senses.
