" Buddhism teaches the doctrine of karma, which is the law of cause and effect relating to our actions. Karma means that whatever one sows, one reaps, be it good or evil. The consequences of meritorious acts are always good. Evil acts, on the other hand, ensure painful retribution. Buddhists are aware that we are constantly creating new karma by our actions. One who believes in the law of causation, therefore, will be careful not to cause pain to people, animals, plants, or the earth itself, for harming them is simultaneously harming oneself. "
" A person of the deepest spirituality will also have a tender concern for every aspect of creation. Such an individual could no more harm a living creature than he or she could harm himself or herself. Buddhist scriptures contend that a bodhisattva will not even walk on grass lest it be harmed. Indeed, the first Buddhist precept is the admonition not to kill, but to cherish all life. This attitude is especially important with respect to food, since anything we eat must die to sustain us. Still, it is less destructive, on a relative level, to take the life of a carrot or an apple than to take that of a more highly evolved form of life, such as a cow, a chicken, or a lobster. Too, from a purely ecological point of view, it is less detrimental to the environment to eat as low as possible on the food chain. All this explains why many Buddhists are vegetarians. "

" Buddhism regards all living creatures as being endowed with the Buddha nature and the potential to become Buddhas. That's why Buddhism teaches us to refrain from killing and to liberate creatures instead. "

" I do not like eating meat because I have seen lambs and pigs killed. I saw and felt their pain. They felt the approaching death. I could not bear it. I cried like a child. I ran up a hill and could not breathe. I felt that I was choking. I felt the death of the lamb. "
