I think 99 times and find nothing. I stop thinking, swim in the silence, and the truth comes to me.

What a deep faith in the rationality of the structure of the world and what a longing to understand even a small glimpse of the reason revealed in the world there must have been in Kepler and Newton to enable them to unravel the mechanism of the heavens in long years of lonely work!

The true measure of a man is the degree to which he has managed to subjugate his ego.

The main task of the spirit is to free man from his ego.

More and more I come to value charity and love of one's fellow being above everything else...All our lauded technological progress-our very civilization-is like the axe in the hand of the pathological criminal.

Arrows of hate have been aimed at me too, but they have never hit me, because somehow they belonged to another world with which I have no connection whatsoever.

I live in that solitude which is painful in youth, but delicious in the years of maturity.
