When we try to pick out anything by itself, we find it hitched to everything else in the universe.
The more clearly we can focus our attention on the wonders and realities of the universe about us, the less taste we shall have for destruction.
It is horrifying that we have to fight our own government to save the environment.
Our task must be to free ourselves by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty.
Animals are such agreeable friends - they ask no questions; they pass no criticisms.
Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures.

Each species is a masterpiece, a creation assembled with extreme care and genius.
