Man is a mystery. It needs to be unravelled, and if you spend your whole life unravelling it, don't say that you've wasted time. I am studying that mystery because I want to be a human being.

Love every leaf, every ray of light. Love the animals, love the plants, love each separate thing. Loving all, you will perceive the mystery of God in all.

The secret of man's being is not only to live but to have something to live for.

Do you know I don't know how one can walk by a tree and not be happy at the sight of it? How can one talk to a man and not be happy in loving him! Oh, it's only that I'm not able to express it...And what beautiful things there are at every step, that even the most hopeless man must feel to be beautiful! Look at a child! Look at God's sunrise! Look at the grass, how it grows! Look at the eyes that gaze at you and love you!

Pain and suffering are always inevitable for a large intelligence and a deep heart. The really great men must, I think, have great sadness on earth.

How does it come about that what an intelligent man expresses is much stupider than what remains inside him?

Man has not the right to turn aside and heed not what is happening in the world around him, and this I maintain on moral grounds of the highest order.
