We learn by rearranging what we know.

We are asleep. Our Life is a dream. But we wake up sometimes, just enough to know that we are dreaming.

Don't think, but look! (PI 66)

When one is frightened of the truth then it is never the whole truth that one has an inkling of.

When we think about the future of the world, we always have in mind its being where it would be if it continued to move as we see it moving now. We do not realize that it moves not in a straight line and that its direction changes constantly.

The world is the totality of facts, not of things

Courage, not cleverness; not even inspiration, is the grain of mustard that grows up to be a great tree.
