1.68

又云。若棄生滅守於真常。常光現時塵根識心應時消落。想相為塵。識情為垢。二俱遠離。則汝法眼應時清明。云何不成無上知覺　佛告阿難。如是清淨持禁戒人心無貪婬。於外六塵不多流溢。因不流溢旋源自歸。塵既不緣根無所偶。反流全一六用不行。十方國土皎然清淨。

It also says: "If you discard arising and ceasing to maintain the true and permanent, when the permanent radiance manifests, the dust, sense faculties, and consciousness-mind will vanish at once. Conceptual marks are the dust; conscious affections are the defilement. When both are left far behind, your Dharma-eye will at once be clear and bright. How could you not achieve unsurpassed awareness?" / The Buddha told Ānanda, "Such a person who purely upholds the prohibitive precepts has a mind without greedy lust, and does not leak or overflow outward toward the six sense objects. Because there is no overflowing, they turn back to the source and return to themselves. Since objects are no longer conditioned, the sense faculties have no counterparts. Reversing the flow to become completely unified, the six functions cease to operate, and the lands of the ten directions become completely clear and pure."
