Guan Yu killed so many people, why did he become a Galand Bodhisattva? Also formed Guan Gong Buddhism? Isn't this against the Buddhist prohibition of killing?

Guan Gong is not a protector of Buddhism, but people admire his comprehensive Confucian personality of loyalty and bravery.

However, on the occasion of Chen Sui, when the wise master, the actual founder of Tiantai Sect, traveled in Yuquan Mountain, Jingzhou, he dreamed that he was a saint, admired the master as a true Buddha, and explained that Fahua was a true religion, hoping that the master would overcome his ignorance.

Accepted, Guan Gong converted to the door of the master and instructed the master to build the temple. Later, the master really got a treasure trove of geomantic omen here, and Lingquan gushed out without digging, so yuquan temple was established, and this temple became the ancestor of Tiantai Sect outside Tiantai Mountain.

The imperial court established Guan Gong as lord protector, and since then Guan Gong has officially changed from a folk righteous god to a Buddhist lord protector, which has been passed down to this day.

It is not an exaggeration to say that Guan Yu Buddhism was formed. Many people worship Guan Yu as the god of wealth, which is true and indeed superstitious. It goes against the essence of Buddhism. Quitting killing is not a strict rule. There are three reasons for abstaining from killing: first, killing is unintentional; Second, crazy and irrational; Third, to save all beings and kill them without committing a crime is a metaphor for killing people who are willing to go to hell in order to save most of them. Although they committed the crime of killing, they did not commit a crime, because their hearts are the spirit of Bodhisattva to save all sentient beings. If you kill people because of a just war, it is innocent. A just war aims at stopping the war, not aggression.
