You must learn to understand the secret of gratitude. It is more than just so-called virtue. It is revealed to you as a mysterious law of existence. In obedience to it we have to fulfill our destiny.

I decided that I would make my life my argument.

Serious illness doesn't bother me for long because I am too inhospitable a host.

I do not want to frighten you by telling you about the temptations life will bring. Anyone who is healthy in spirit will overcome them. But there is something I want you to realize. It does not matter so much what you do. What matters is whether your soul is harmed by what you do. If your soul is harmed, something irreparable happens, the extent of which you won't realize until it will be too late.

Love is the only thing that increases twofold every time it is shared.

Whatever you have received more than others-in health, in talents, in ability, in success, in a pleasant childhood, in harmonious conditions of home life-all this you must not take to yourself as a matter of course. In gratitude for your good fortune, you must remember in return some sacrifice of your own life for another life.

Ethics cannot be based upon our obligations toward people, but they are complete and natural only when we feel this Reverence for Life and the desire to have compassion for and to help all creatures insofar as it is in our power. I think that this ethic will become more and more recognized because of its great naturalness and because it is the foundation of a true humanism toward which we must strive if our culture is to become truly ethical.
