[1388] One who will not fully understand (parijānissati) the eye faculty (cakkhundriya) — will that one not realize (sacchikarissati) the perfect-knower faculty (aññātāvindriya)?
One endowed with the supreme path (aggamaggasamaṅgī) will not fully understand the eye faculty, yet it is not the case that he will not realize the perfect-knower faculty. Two persons will both not fully understand the eye faculty and not realize the perfect-knower faculty.
Or rather: one who will not realize the perfect-knower faculty — will that one not fully understand the eye faculty? Yes.
