Never let oneself be guided by the opinion of one's contemporaries. Continue steadfastly on one's way.

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.

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 have become a different person. I don't know whether this person is better, he certainly is not happier.
