Monasticism, also called monachism or monkhood, is a religious way of life in which one renounces worldly pursuits to devote oneself fully to spiritual work. 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 criticized and not practiced, as in Islam and Zoroastrianism, or plays a marginal role, as in modern Judaism.
Forest dwelling was a common practice in early Buddhism, and it is still followed by some Buddhist sects such as the Thai Forest Tradition.
