The first way is not to eat meat. That is, the meat of various animals, even eggs. Monks are not allowed to eat this kind of food. in addition

The concept of vegetarianism includes not eating "meat" and "fish". "Meat" refers to vegetables with fishy smell and peculiar smell, such as garlic, green onions and leeks. The Shurangama Sutra says: raw meat makes you angry, and cooked food helps you to be immoral. So Buddhism requires fasting.

The second way is to eat meat. Sakyamuni Buddha believes that Sanjin meat is edible, which refers to the meat of animals that believers have never seen, heard of or suspected of killing for themselves. There is also the saying of "five clean meats", that is, the above three kinds plus the meat left after natural death and being killed by other birds and animals.

Extended data:

First, fasting:

Bean products, milk and dairy products, such as cheese, raw crisp, etc. , and it is not prohibited. In addition, Buddhism also requires monks not to drink or smoke. Not drinking also includes not drinking all kinds of intoxicating drinks, such as japonica rice wine, fruit wine, highland barley wine, beer and so on. All kinds of "drugs" that anesthetize nerves and the secretory system are taboo.

Although smoking is not within the scope of the Five Commandments, it is a bad habit or hobby of spiritual dependence, reflecting a spiritual pursuit and greed, which is inconsistent with the pure and selfless realm required by Buddhism, so smoking is of course one of the taboos of Buddhism.

Second, three clean meat records:

Buddhism advocates not killing, but generally allows eating three golden meats. The forty-second volume of the law of four points stipulates:

There are three reasons for unclean meat. I said don't eat. If you see me killed, If you hear from someone you trust that you killed someone for me. If you see a head, skin and hair at home. If you see blood on your feet. Again, this man is heinous and often kills people. You can kill for me. Don't eat meat if the three causes are unclean. There are three kinds of clean meat to eat. If you don't see it, smell it or doubt it, you should eat it. If you don't kill for me, I don't smell it. Kill it for me. If you can't see your head, feet, fur and blood at home. That man is not the murderer.
