弃绝期（梵文：saṁnyāsa），是印度教再生族人生最后一个阶段，在这个阶段信徒放弃世俗和物质追求把生命奉献给精神生活，目标是去除所有的无知，实现自己和梵为一体。实践者称桑耶西。

在弃绝期，桑耶西只可托钵乞讨由信徒供养，而他通过给信徒教导来给别人树立一个榜样。

由于他们已出家失去种姓，如还俗结婚子女一律成为贱民。

由于他们已举行一次生前葬故不得生火，死后不火化，而是由其他桑耶西埋葬。

Sannyasa (saṃnyāsa) is the life stage of renunciation within the Hindu philosophy of four age-based life stages known as ashramas, 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 the householder and retirement stages, renounce worldly and materialistic pursuits and dedicate their lives to spiritual pursuits (moksha).
