“The basic foundation of the practice of morality is to refrain from ten unwholesome actions: three pertaining to the body, four pertaining to speech, and three pertaining to thought. The three physical non-virtues are: (1) killing: intentionally taking the life of a living being, whether a human being, an animal, or even an insect; (2) stealing: taking possession of another’s property without his or her consent, regardless of its value; and (3) sexual misconduct: committing adultery. The four verbal non-virtues are: (4) lying: deceiving others through spoken word or gesture; (5) divisiveness: creating dissension by causing those in agreement to disagree or those in disagreement to disagree further; (6) harsh speech: verbally abusing others; and (7) senseless speech: talking about foolish things motivated by desire and so forth. The three mental non-virtues are: (8) covetousness: desiring to possess something that belongs to someone else; (9) harmful intent: wishing to injure others, whether in a great or small way; and (10) wrong view: holding that such things as rebirth, the law of cause and effect, or the Three Jewels8 do not exist.”
