Shravasti Dhammika, To EAT OR NOT TO EAT MEAT: A BUDDHIST REFLECTION
Chapter 3 Motivation and meat
2. The Buddha gave three reasons why we should take ethical discipline seriously:
(1) The first is to avoid the negative effects of bad actions – usually called ‘bad kamma’ but more correctly ‘bad vipaka’. This is mentioned by the Buddha many times and is the only one of the three that is ever mentioned in traditional Theravada teaching, giving rise, with some justification, to the criticism that Theravada is selfish.
(2) The second reason is because following the Precepts lays the foundation for positive qualities like restraint, awareness, mental clarity, the happiness of having a clear conscience (anavajja sukha, Digha Nikaya I,70), etc. and which in time lead to the ultimate good, Nirvana.

(1) 首先是避免惡行的影響 — 通常稱為「惡業」，但正確一點應是「惡果報」(Vipāka)。佛陀曾多次提及這點。它是三個提到的上座部傳統教義當中，唯一有些理由導致上座部佛教被批評為自私的教義。
(2) 第二個原因是五戒為良好的品德奠下基礎，例如克己、覺悟力、頭腦清晰和戒除惡業的快樂 (anavajja sukha, 《長部》I, 70) 等，它日後能帶來終極的快樂 — 涅槃。
