Nitya-samsarins (Sanskrit: नित्यसंसारिन्, romanized: nityasaṃsārin) or nitya-samsaris is a concept in Hindu philosophy, referring to an individual who believes that their self is eternally bound in the cycle of rebirth called samsara. The existence of nitya-samsari is used to offer credibility to the concept of the periodical creation and the dissolution of the universe.[1][2][3]
