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.

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

The man who has become a thinking being feels a compulsion to give every will-to-live the same reverence for life that he gives to his own. He experiences that other life in his own.

Man's ethics must not end with man, but should extend to the universe. He must regain the consciousness of the great Chain of Life from which he cannot be separated.

Kindness works simply and perseveringly; it produces no strained relations which prejudice its working; strained relations which already exist it relaxes. Mistrust and misunderstanding it puts to flight, and it strengthens itself by calling forth answering kindness. Hence it is the furthest reaching and the most effective of all forces.

When man learns to respect even the smallest being of creation...nobody has to teach him to love his fellow man. Compassion for animals is intimately connected with goodness of character, and it may be confidently asserted that he who is cruel to animals cannot be a good man.

As we acquire knowledge, things do not become more comprehensible, but more mysterious.
