Sotāpanna
In Buddhism, a sotāpanna (Pali) or srotāpanna (Sanskrit)—translated variously as "stream-enterer", "stream-entrant" or "stream-winner"—is one who has reached the first of the four stages of enlightenment. Stream entry is purportedly followed by three subsequent stages of awakening: Sakadāgāmi (once-returner), Anāgāmi (non-returner), and Arahant (fully liberated).
