[1362] Whoever developed the faculty "I shall come to know the unknown" (anaññātaññassāmītindriya), did that one develop the perfect-knowledge faculty (aññindriya)?
Six persons (puggalā) developed the faculty "I shall come to know the unknown" but did not develop the perfect-knowledge faculty; the Arahant (arahā) both developed the faculty "I shall come to know the unknown" and developed the perfect-knowledge faculty.
Or rather, whoever developed the perfect-knowledge faculty, did that one develop the faculty "I shall come to know the unknown"?
Yes.
