Both asceticism and monasticism have been adopted by worshipers of various faiths. In general, asceticism is the practice of strict self-denial as a means of attaining a higher spiritual plane. Monasticism is the state of being secluded from the world in order to fulfill religious vows.
Asceticism was practised in biblical times, and events like the temptations of Jesus in the wilderness and the lifestyle of John the Baptist in the desert were later regarded as helpful models when monasticism became the leading representation of asceticism.
