For animals that are overworked, underfed, and cruelly treated; for all wistful creatures in captivity that beat their wings against bars; for any that are hunted or lost or deserted or frightened or hungry; for all that must be put to death...and for those who deal with them we ask a heart of compassion and gentle hands and kindly words.

Don't stop to ask whether the animal or plant you meet deserves your sympathy, or how much it feels, or even whether it can feel at all: respect it and consider all life sacred.

We should all be thankful for those people who rekindle the inner spirit.

Truth has not special time of its own. Its hour is now - always and, indeed then most truly, when it seems unsuitable to actual circumstances.

The future of civilization depends on our overcoming the meaninglessness and hopelessness which characterize the thoughts and convictions of men today, and reaching a state of fresh hope and fresh determination.

Sincerity is the foundation of the spiritual life.

Rational thinking which is free from assumptions ends therefore in mysticism. To relate oneself in the spirit of reverence for life to the multiform manifestations of the will-to-live which together constitute the world is ethical mysticism. All profound world-view is mysticism, the essence of which is just this: that out of my unsophisticated and naïve existence in the world there comes, as a result of thought about self and the world, spiritual self-devotion to the mysterious infinite Will which is continuously manifested in the universe.
