"Bhikkhus,possessing five things,a bhikkhu in no long time penetrates to the unshakable.
Akuppam.Probably meaning akuppa cetovimutti,unshakable liberation of mind.Mp identifies this with arahantship.
What five?
[120]Here,a bhikkhu has attained the analytical knowledge of meaning,the analytical knowledge of the Dhamma,the analytical knowledge of language,and the analytical knowledge of discernment;and he reviews the extent to which his mind is liberated.
Possessing these five things,a bhikkhu in no long time penetrates to the unshakable."
