“Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.”

“I believe in you and me. I'm like Albert Schweitzer and Bertrand Russell and Albert Einstein in that I have a respect for life -- in any form. I believe in nature, in the birds, the sea, the sky, in everything I can see or that there is real evidence for. If these things are what you mean by God, then I believe in God. But I don't believe in a personal God to whom I look for comfort or for a natural on the next roll of the dice.”

“We must fight against the spirit of unconscious cruelty with which we treat the animals. Animals suffer as much as we do. True humanity does not allow us to impose such sufferings on them. It is our duty to make the whole world recognize it. Until we extend our circle of compassion to all living things, humanity will not find peace.”

“The fundamental principle of morality which we seek as a necessity for thought is not, however, a matter only of arranging and deepening current views of good and evil, but also of expanding and extending these. A man is really ethical only when he obeys the constraint laid on him to help all life which he is able to succour, and when he goes out of his way to avoid injuring anything living. He does not ask how far this or that life deserves sympathy as valuable in itself, nor how far it is capable of feeling. To him life as such is sacred. He shatters no ice crystal that sparkles in the sun, tears no leaf from its tree, breaks off no flower, and is careful not to crush any insect as he walks. If he works by lamplight on a summer evening, he prefers to keep the window shut and to breathe stifling air, rather than to see insect after insect fall on his table with singed and sinking wings.”

“He who does not reflect his life back to God in gratitude does not know himself.”

“A man is ethical only when life, as such, is sacred to him, that of plants and animals as that of his fellow men, and when he devotes himself helpfully to all life that is in need of help.”

“A great secret of success is to go through life as a man who never gets used up.”

“Life becomes harder for us when we live for others, but it also becomes richer and happier.”

“Until he extends his circle of compassion to include all living things, man will not himself find peace.”

“Do something wonderful, people may imitate it.”
