2. Weaker

In Brief (2nd)

“Bhikkhus, there are these five faculties. What five? The faculties of faith, energy, mindfulness, samādhi, 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 the teachings … a follower by faith.

So from a diversity of faculties there’s a diversity of fruits. And from a diversity of fruits there’s a diversity of persons.”
