This world that you see around you is not the real world. Not that it doesn't exist. It exists -- but you are seeing it through a screen of sleep, an unconsciousness is in between. You look at it, you interpret it in your own way; you are just like a drunkard.
It happened: Mulla Nasruddin came running. He was totally drunk and the man who was operating the elevator was just going to close the door, but he somehow pushed in. It was overcrowded. Everybody became aware that he was very drunk; his breath was smelling. He tried to pretend; he tried to face towards the door, but he couldn't see anything -- his eyes, too, were drunk and sleepy. Somehow he was trying to stand, but that was not possible either. And then he felt very much embarrassed, because everybody was looking and everybody was thinking that he was completely drunk; he could feel that. Then he suddenly forgot where he was and he said, "You must be wondering why I called this meeting." Seeing that so many people were around, he thought that he had called a meeting and that the people were wondering why. By the morning he will be okay. He will himself laugh as you are laughing.
All buddhas have laughed when they awaken. Their laughter is like a lion's roar. They laugh, not at you, they laugh at the whole cosmic joke. They lived in a dream, in a sleep, intoxicated completely by desire, and through desire they looked at the existence. Then it was not the real existence, they projected their own sleep on it.
You are taking the whole existence as a screen, and then you project your own mind on it and you see things which are not there, and you don't see things which are there. And the mind has explanations for everything. If you raise a doubt, the mind explains. It creates theories, philosophies, systems, just to feel comfortable, that nothing is wrong. All philosophies exist to make life convenient, so that everything looks okay, nothing is wrong -- but everything is wrong while you are asleep.
One man came to me. He was worried; he is the father of a beautiful daughter. He was very much worried. He said, "Every morning she feels a little sick, and I have been to all the doctors and they say nothing is wrong. So what to do?"
So I told him, "You go to Mulla Nasruddin -- he is the wise guy around here and he knows everything, because I have never heard him say, 'I don't know.' You go."
He went. I also followed just to see what Nasruddin would say. Nasruddin closed his eyes, contemplated on the problem, then he opened his eyes and said, "Do you give her milk before she goes to bed at night?"
The man said, "Yes!" Nasruddin said, "Now, I have found the problem: if you give milk to a child, then the child changes sides the whole night from right to left, from left to right, and through the churning the milk becomes curd. Then the curd becomes cheese, then the cheese becomes butter, then the butter becomes fat, then the fat becomes sugar, then the sugar becomes alcohol -- and, of course, in the morning she has a hangover."
This is what all the philosophies are: some explanations of things; some explanation of things which cannot be explained; pretending to know about something which is not known.
But they make life convenient. You can sleep better, they are like tranquilizers.
Remember, this is the difference between religion and philosophy: philosophy is a tranquilizer, religion is a shock; philosophy helps you to sleep well, religion brings you out of sleep. Religion is not a philosophy -- it is a technique to bring you out of your unconsciousness. And all philosophies are techniques to help you to sleep well; they give you dreams, utopias.
