As for merit, as long as you are chanting Buddha, you must have merit, but the five desires to eat meat will be discounted.
Q: Can people who eat meat recite Buddha?
A: Buddha is based on compassion. If you eat meat, you have no sympathy. This is for your real yogi. If casual people are not vegetarians, they can also read Buddha. If you have to eat meat, you can't read Buddha. You must know. ("Paper Money" has three volumes and two volumes, and Chen's "Female laity book")
Purity makes sense. Although the situation is difficult, it is better to eat less. When preparing for dinner, you should also have a compassionate heart. People who eat meat can't recite Buddha. (paper money, three volumes, three copies of the common people's Sect)
The so-called meat is five coriander, and there are three kinds of daily use: onion, garlic and leek. Because of the bad smell, the Shurangama Sutra says: "Raw food increases the gap, and cooked food is obscene." It is forbidden by Buddhism.
The so-called fishy smell is the flesh and blood of animals. Buddhism is the most compassionate religion, so we should care for all beings. How can you care if you eat other people's meat? But in fact, in this world, the land is barren and people don't have enough to eat. What is the choice? So Buddhism came up with a flexible way, that is, the so-called "three clean meats" and "five clean meats" can be eaten. The details are complicated, and I can't remember them all, but the general idea is that you didn't kill him, you didn't see anyone kill him, you didn't hear the screams when he died, you didn't find someone to kill him, and no one else came to kill him for you. The meat in the supermarket should be fine. Another possibility is that he died by himself, which is basically meaningless to modern people who pay attention to food hygiene.
Of course, strict Buddhists should give up completely. It is said in the Shurangama Sutra that practitioners should not trample on living grass when walking on the road. Why does he feed on the flesh and blood of all beings?
The combination of meat and fish is called meat and fish.
