注大乘入楞伽經 6.155

6.155

This means that one's own noble wisdom awakens to the fact that all objective realms lack reality, like the moon in water, and thus there is neither exiting nor entering. It also says that the nature of wisdom is inherently luminous and certainly not subject to arising and ceasing; it is only termed 'arising' when free of delusion, and called 'ceasing' when obscured by delusion. Just as when water is clear the moon appears, and when water is turbid the reflection is submerged, yet the nature of the moon remains constantly so, originally having neither entering nor exiting.
