Why are onions a meat dish?

As for the "five meat dishes" mentioned in the Shurangama Sutra, the top of the giant Buddha, you should know that "meat" is a grass prefix, and meat is not meat; The meat smells of fish. Meat and fish should be separated. Meat and fish are different. Meat is a plant and fish is an animal. These five spices are: onion, garlic, leek, onion and mustard head. It is harmful for the Buddha to say these words to beginners and people who have not yet achieved their studies. Eating these five lucky things will make the physiology reflect. Eating raw is easy to get angry; Cooked food is easy to produce hormones and cause sexual impulses. Hinder the purity of the mind and hinder the correction. This is the reason for not eating. From this we know that whether to break the "five desires" (in fact, it should be called "five meats") mainly depends on the individual's learning ability and practical work ability.
