Aṅguttara Nikāya 5.95 10. Kakudhavagga Akuppasutta

“Pañcahi, bhikkhave, dhammehi samannāgato bhikkhu nacirasseva akuppaṁ paṭivijjhati.

“Mendicants, a mendicant who has five things will soon penetrate the unshakable.

Katamehi pañcahi?

What five?

Idha, bhikkhave, bhikkhu atthapaṭisambhidāpatto hoti, dhammapaṭisambhidāpatto hoti, niruttipaṭisambhidāpatto hoti, paṭibhānapaṭisambhidāpatto hoti, yathāvimuttaṁ cittaṁ paccavekkhati.

It’s when a mendicant has attained the textual analysis of meaning, text, definition, and eloquence, and they review the extent of their mind’s freedom.

Imehi kho, bhikkhave, pañcahi dhammehi samannāgato bhikkhu nacirasseva akuppaṁ paṭivijjhatī”ti.

A mendicant who has these five things will soon penetrate the unshakable.”

Pañcamaṁ.
