Do you want to live happily? Travel with two bags, one for giving, the other for receiving.

Let there be truth between us.

One man's word is no man's word; we should quietly hear both sides.

Science and art belong to the whole world, and before them vanish the barriers of nationality.

By nature we have no defect that could not become a strength, no strength that could not become a defect.

Everyone holds his fortune in his own hands, like a sculptor the raw material he will fashion into a figure. But it's the same with that type of artistic activity as with all others: We are merely born with the capability to do it. The Skill to mold the material into what we want must be learned and attentively cultivated.

One must keep repeating the Truth.
