Though most Burmese eat meat, some prominent Burmese Buddhist monks have promoted vegetarianism as a wholesome and compassionate diet. These figures include the popular Thamanya Sayadaw and his followers, who promote a vegetarian diet as a useful way to cultivate metta. Mahasi Sayadaw has also recommended vegetarianism as the best way to make sure one's meal is "pure in three ways." This refers to the rule the Buddha laid down which allows monks to eat meat only if it is not seen, heard or suspected that the animal was killed specifically for them. Burmese Buddhists also generally avoid jobs which entail the killing of animals, since it would be a wrong livelihood.
