justified by the authors because protecting Buddhism was seen as more important than keeping the precepts. Another example that is often cited is that of King Duṭṭhagāmaṇī, who is mentioned in the post-canonical Pāli Mahāvaṃsa chronicle. In the chronicle, the king is saddened with the loss of life after a war, but comforted by a Buddhist monk, who states that nearly everyone who was killed did not uphold the precepts anyway. Buddhist studies scholar Lambert Schmithausen argues that in many of these cases Buddhist teachings like that of emptiness were misused to further an agenda of war or other violence. In practice Field studies in Cambodia and Burma have shown that many Buddhists considered the first precept the most important, or the most blamable. In some traditional communities, such as in Kandal Province in pre-war Cambodia, as well as Burma in the 1980s, it was uncommon for Buddhists to slaughter animals, to the extent that meat had to be bought from non-Buddhists. In his field studies in Thailand in the 1960s, Terwiel found that villagers did tend to kill insects, but were reluctant and self-conflicted with regard to killing larger animals. In Spiro's field studies, however, Burmese villagers were highly reluctant even to kill insects. Early Buddhists did not adopt a vegetarian lifestyle. Indeed, in several Pāli texts vegetarianism is described as irrelevant in the spiritual purification of the mind. There are prohibitions on certain types of meat, however, especially those which are condemned by society. The idea of abstaining from killing animal life has also led to a prohibition on professions that involve trade in flesh or living beings, but not to a full prohibition of all agriculture that involves cattle. In modern times, referring to the law of supply and demand or other principles, some Theravādin Buddhists have attempted to promote vegetarianism as part of the five precepts. For example, the Thai Santi Asoke movement practices vegetarianism. Furthermore, among some schools of Buddhism, there has been some debate with regard to a principle in the monastic discipline. This principle states that a Buddhist monk cannot accept meat if it comes from animals especially slaughtered for him. Some teachers have interpreted this to mean that when the recipient has no knowledge on whether the animal has been killed for him, he cannot accept the food either. Similarly, there has been debate as to whether laypeople should be vegetarian when
