Tatiyasaṁkhitta sutta: In Brief (3rd)

“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, mendicants, if you practice partially you succeed partially. If you practice fully you succeed fully. But in any case, these five faculties are not barren, I say.”
