 Asceticism in Indian religions includes a spectrum of diverse practices, ranging from the mild self-discipline, self-imposed poverty and simple living typical of Buddhism and Hinduism, to more severe austerities and self-mortification practices of monks in Jainism and now extinct Ajivikas in the pursuit of salvation.Some ascetics live as loner hermits relying on whatever food they can find in the forests, then sleep and meditate in caves; others travel from one holy site to another while sustaining their body by begging for food; yet others live in monasteries as monks or nuns.Some ascetics live like priests and preachers, other ascetics are armed and militant, to resist any persecution – a phenomenon that emerged after the arrival of Islam in India.
