Monasticism (from Ancient Greek μοναχός, monakhos, from μόνος, monos, 'alone'), also referred to as 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.
Many monastics live in abbeys, convents, monasteries or priories to separate themselves from the secular world, unless they are in mendicant or missionary orders.
The Sangha or community of ordained Buddhist bhikkhus (Pali bhikkhu, like Sanskrit bhikṣu, means 'beggar; one who lives by alms'), and original bhikkhunīs (nuns) were founded by Gautama Buddha during his lifetime over 2500
