„Teach thy tongue to say, “I do not know,” and thous shalt progress.”

Learn from yesterday, live for today, hope for tomorrow. The important thing is not to stop questioning.

The water in a vessel is sparkling; the water in the sea is dark. The small truth has words that are clear; the great truth has great silence.

Don't lose yourself in the process of loving others.

The moment you fear, you are nobody. It is fear that is the great cause of misery in the world.

Avoid the temptation to work so hard that there is no time left for serious thinking.

I'm sick and tired of being sick and tired.
