Ascetics and Sadhus of India and Nepal.
Sadhus or holy men are inherent to the Hindu religion. The fourth phase in a Hindu's life, after studying, being a father and a pilgrim, is asceticism. The term sadhu, or holy man refers to mystics, ascetics, yogis, and mendicant monks who live apart of society.
They cut all family ties, no possessions and reduce to the minimum their needs, to focus on reach a higher reality. They depend of the charity of people to subsist because they can not work, and donations made to them are considered as "offerings to the Gods' favoring greater accumulation of good karma.
