Dutiyasaṁkhitta sutta: In Brief (2nd)

“Mendicants, there are these five faculties. What five? The faculties of faith, energy, mindfulness, immersion, and wisdom. These are the five faculties.

Someone who has completed and fulfilled these five faculties is a perfected one. If they are weaker than that, they’re a non-returner … a once-returner … a stream-enterer … a follower of teachings … a follower by faith.

So from a disparity of faculties there’s a disparity of fruits. And from a disparity of fruits there’s a disparity of individuals.”
