The tragedy of life is what dies inside a man while he lives.

Today . . . we know that all living beings who strive to maintain life and who long to be spared pain - all living beings on earth - are our neighbors.

Joy, sorrow, tears, lamentation, laughter -- to all these music gives voice, but in such a way that we are transported from the world of unrest to a world of peace, and see reality in a new way, as if we were sitting by a mountain lake and contemplating hills and woods and clouds in the tranquil and fathomless water.

Soldiers' graves are the greatest preachers of peace.

It is through the idealism of youth that man catches sight of truth, and in that idealism he possesses a wealth which he must never exchange for anything else.

No ray of sunlight is ever lost, but the green which it awakes into existence needs time to sprout, and it is not always granted to the sower to see the harvest. All work that is worth anything is done in faith.

The doctor of the future will be oneself.
