“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 practicing to realize the fruit of perfection … a non-returner … practicing to realize the fruit of non-return … a once-returner … practicing to realize the fruit of once-return … a stream-enterer … practicing to realize the fruit of stream-entry. Someone who totally and utterly lacks these five faculties stands outside in the faction of ordinary persons, I say.”

“Sir, they speak of someone who is ‘accomplished in the faculties’. How is someone accomplished in the faculties defined?” “Mendicant, it’s when a mendicant develops the faculties of faith, energy, mindfulness, immersion, and wisdom that lead to peace and awakening. This is how someone who is accomplished in the faculties is defined.”
