(Sanskrit सकृदागामिन्) "returning only once again i.e. being re-born, once-returner." In Pail, the term is sakadagami. A term used by the Buddha Shakyamuni when he described four levels or degrees of attainment. Sakridagamin is the second degree. In Sutrayana (Foundational Path) of Buddhism, sakridagamin is understood in a exoteric manner and each school has its own way of applying the term. In esotericism, sakridagamin is very specific: it refers to those who have completed the second degree of Major Mysteries, the second of the seven serpents of Kundalini / Candali.
