The call of love sounds very hollow among these immobile rocks.

I am thrice homeless, as a native of Bohemia in Austria, as an Austrian among Germans, and as a Jew throughout the world. Everywhere an intruder, never welcomed.

I also had a brother who was like me a musician and a composer. A man of great talent, far more gifted than I. He died very young... he killed himself in the prime of his life.

The impressions of the spriritual experiences gave my future life its form and content.

When I have reached a summit, I leave it with great reluctance, unless it is to reach for another, higher one.

You must renounce all superficiality, all convention, all vanity and delusion.
