Asceticism (from the Greek: ἄσκησις, áskēsis, "exercise" or "training") describes a lifestyle characterized by abstinence from various worldly pleasures, often with the aim of pursuing religious and spiritual goals. Many religious traditions (e.g. Buddhism, Jainism, the Christian Desert Fathers) include practices that involve restraint with respect to actions of body, speech, and mind. The founders and earliest practitioners of these religions lived extremely austere lifestyles, refraining from sensual pleasures and the accumulation of material wealth. They practiced asceticism not as a rejection of the enjoyment of life, or because the practices themselves are virtuous, but as an aid in the pursuit of salvation or liberation.
