The Four Path Model
The Four Path Model in its traditional form is the oldest of the Buddhist maps of enlightenment. It describes four progressive stages of awakening:
- First Path, aka stream entry, sotapana in Pali
- Second Path, aka once returner, sakadagami in Pali
- Third Path, aka never returner, anagami in Pali
- Fourth Path, aka Conquerer, Saint, Holy One, in Pali arahat, also spelled arhat or arahant
There are various ways to define these terms and use them.
For a discussion of how they tend to be used here on the DhO, it is highly recommended to look here: MCTB, more specifically here MCTB Models of the Stages of Enlightenment, and even more specifically MCTB The Theravada Four Path Model, as well as MCTB Was that Emptiness
