The Theravada four-path model has four stages of awakening, namely first path: “stream enterer” or in Pali, sotapanna; second path: “once-returner” or sakadagami; third path: “non-returner” or anagami; and, finally, fourth path, which gets translated in various ways in various sources, with some including “perfected person”, “holy one”, “saint”, or “conqueror” (one who has conquered the defilements that prevented the realization of nibbana), or arhat, arahant, or arhant, pick your favorite spelling, but I will use arahant, realizing that I used arahat in the previous version.
