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.
The practitioners of these religions eschewed worldly pleasures and led an abstinent lifestyle, in the pursuit of redemption, salvation or spirituality. Asceticism is seen in the ancient theologies as a journey towards spiritual transformation, where the simple is sufficient, the bliss is within, the frugal is plenty.
