[1413] Whoever does not develop the 'I shall come to know the unknown' faculty (anaññātaññassāmītindriya), has that person not realized the perfect-knower faculty (aññātāvindriya)?
The Arahant does not develop the 'I shall come to know the unknown' faculty, but it is not that he has not realized the perfect-knower faculty. Seven persons do not develop the 'I shall come to know the unknown' faculty and have not realized the perfect-knower faculty.
Or, whoever has not realized the perfect-knower faculty, does that person not develop the 'I shall come to know the unknown' faculty?
The eighth person (aṭṭhamaka) has not realized the perfect-knower faculty, but it is not that he does not develop the 'I shall come to know the unknown' faculty. Seven persons have not realized the perfect-knower faculty and do not develop the 'I shall come to know the unknown' faculty.
