asceticism
The origins of asceticism lie in man’s attempts to achieve various ultimate goals or ideals: development of the “whole” person, human creativity, ideas, the “self,” or skills demanding technical proficiency. Athletic askēsis, involving the ideal of bodily fitness and excellence, was developed to ensure the highest possible degree of physical fitness in an athlete. Among the ancient Greeks, athletes preparing for physical contests disciplined their bodies by abstaining from various normal pleasures and by enduring difficult physical tests. In order to achieve a high proficiency in the skills of warfare, warriors also adopted various ascetical practices. The ancient Israelites, for example, abstained from sexual intercourse before going into battle.
Asceticism the practice of the denial of physical or psychological desires in order to attain a spiritual ideal or goal. Hardly any religion has been without at least traces or some features of asceticism.
