A monk asked: "How can we know when every sort of karmic hindrance has been wiped out?"
Master Hui-Hai answered:
When you suddenly perceive your own Mind, you will at that moment understand the affairs of the past and those of the future as if they were right before your very eyes. All past and future, as well as present, dharmas will be perceived simultaneously. The Sutra says, "All the dharmas known by your purified mind constitute the Bodhimandala, which is the totality of all Wisdom."
Hui-Hai also commented: "[In reality] there is only no mind whatsoever dwelling nowhere at all. When this stage is reached, one is, quite naturally, liberated." -Hui-Hai
