Asceticism, << uh SEHT uh sihz uhm, >> is the practice of self-denial or self-punishment, often for religious purposes. People who practice asceticism are called ascetics. They may go for long periods without food or sleep, wear rough clothing, expose themselves to extreme heat or cold, or refrain from sexual relations. Some even whip themselves or stick sharp objects in their skin.
Ascetics believe a person’s physical life conflicts with his or her spiritual life. Ascetics strive to become more spiritual by denying themselves physical pleasures and many necessities. Sometimes, ascetic practices produce religious visions, which ascetics regard as a sign of their increasing spirituality.
Asceticism has been a part of religious traditions for thousands of years. Many early Christians gave up physical comforts to become closer to God. Asceticism has been especially important in Roman Catholicism and certain religions of India and Japan.
