Three of body, four of speech, three of mind
The Sāleyyaka Sutta (MN 41) describes each one concretely. In body, the person who acts wholesomely has laid down rod and weapon, is conscientious and kind, and has compassion for all living beings; does not take others’ belongings that were not given, whether in the village or in the forest; and does not commit sexual misconduct with anyone protected by family, a spouse or the law. In speech, when called as a witness, they say “I know” only when they know and “I don’t know” when they don’t; they do not repeat here what was said there in order to divide, but reconcile those at odds; they speak gently, pleasantly, in words that go to the heart; and they speak at the right time, truthfully and meaningfully, words worth remembering. In mind, they do not wish others’ property were theirs, do not wish anyone harm but wish all beings to live free of enmity and at ease, and see rightly that good and bad deeds bear fruit.
