To live is to act, and our actions can have either harmful or beneficial consequences for oneself and others. Buddhist ethics is concerned with the principles and practices that help one to act in ways that help rather than harm. The core ethical code of Buddhism is known as the five precepts, and these are the distillation of its ethical principles. The precepts are not rules or commandments, but ‘principles of training’, which are undertaken freely and need to be put into practice with intelligence and sensitivity. The Buddhist tradition acknowledges that life is complex and throws up many difficulties, and it does not suggest that there is a single course of action that will be right in all circumstances. Indeed, rather than speaking of actions being right or wrong, Buddhism speaks of the being skilful (kusala) or unskilful (akusala).
