“There are another six things, which are six sources of conflict: [1] If a monk is extremely angry and doesn’t let it go, he doesn’t respect the Tathāgata, doesn’t respect the Dharma, and doesn’t respect the Saṅgha. His precepts are breached, and he’s defiled and impure. When he creates many conflicts in the Saṅgha, he’s disliked by people, disrupts the pure assembly, and gods and people don’t attain peace.
