There is also a continuous dialogue between the two. People in the West need to look at the harm done to animals. Animals are slaughtered by the millions for the Western palate. This is unnecessary and avoidable. Sensitivity to all forms of life is an important value.
Yoga encourages an optimal diet.
The Western Yoga traditions may have somewhat different answers based on the physiological, chemical and biochemical advances in knowledge, but in essence their answers will coincide with the nonviolent ethics of vegetarianism. Yoga practitioners should become vegetarian. Most of the Indic and Eastern traditions subscribe to reincarnation. Some medieval siddhas in Tamil Nadu debunked reincarnation, but these are rare exceptions. I personally like the Buddhist interpretation of reincarnation.
