In the East Asian Buddhism, most monastics are expected to be vegetarian, and the practice is seen as very virtuous and it is taken up by some devout laypersons. Most Theravadins in Sri Lanka and Southeast Asia do not practice vegetarianism and eat whatever is offered by the lay community, who are mostly also not vegetarians. But there are exceptions, some monks choose to be vegetarian and some abbots like Ajahn Sumedho have encouraged the lay community to donate vegetarian food to the monks. Mahasi Sayadaw meanwhile, has recommended vegetarianism as the best way to make sure one's meal is pure in three ways. Also, the new religious movement Santi Asoke, promotes vegetarianism. According to Peter Harvey, in the Theravada world, vegetarianism is "universally admired, but little practiced." Because of the rule against killing, in many Buddhist countries, most butchers and others who work in the meat trade are non-Buddhists.
