Sannyasa is the life stage of renunciation within the Hindu philosophy of four age-based life stages known as ashrams, with the first three being Brahmacharya (bachelor student), Grihastha (householder) and Vanaprastha (forest dweller, retired). Sannyasa is traditionally conceptualized for men or women in late years of their life, but young Brahmacharis have had the choice to skip householder and retirement stage, renounce worldly and materialistic pursuits and dedicate their lives to spiritual pursuits (moksha).

Sannyasa is a form of asceticism, is marked by renunciation of material desires and prejudices, represented by a state of disinterest and detachment from material life, and has the purpose of spending one's life in peaceful, love-inspired, simple spiritual life.
