The greatest enemy of knowledge is not ignorance, it is the illusion of knowledge.

Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world.

My brain is only a receiver, in the Universe there is a core from which we obtain knowledge, strength and inspiration. I have not penetrated into the secrets of this core, but I know that it exists.

There's no one thing that's true. It's all true.

The most important knowledge is that which guides the way you lead your life.

If you tell the truth, you don't have to remember anything.

I believe in God, but not as one thing, not as an old man in the sky. I believe that what people call God is something in all of us. I believe that what Jesus and Mohammed and Buddha and all the rest ...

Always go too far, because that's where you'll find the truth.

We may have all come on different ships, but we’re in the same boat now.
