I just wanted to share this video from the famous Chinese monk, Sheng-Yen (聖嚴, died in 2009) about Buddhism and vegetarianism:
I liked this video because it was pretty balanced. He lays out some good, valid reasons why some Buddhists are vegetarian, but he also lays out reasons why some are not. A lot of it depends on which Buddhist tradition, and also the circumstances in your life. It’s a voluntary, pious practice, but not required in Buddhism (unless you belong to some monastic orders).
