Monasticism, also called monachism or monkhood, is a religious way of life in which one renounces worldly pursuits to devote oneself fully to spiritual activities. Monastic life plays an important role in many Christian churches, especially in the Catholic, Orthodox and Anglican traditions as well as in other faiths such as Buddhism, Hinduism, and Jainism. In other religions, monasticism is generally criticized and often explicitly forbidden, as in Islam, Sikhism and Zoroastrianism; or plays a marginal role, as in modern Judaism.
