Means reality in Buddhist concept.

In Tibetan Dzogchen, reality is emptiness, which means that after you accept and see the things as they really are, they don't mean anything, they are only a kind of perception, and they are representation of deities.

Before you recognize the suchness in thing, you cannot perceive the thing as they really are because of the limitation of human body.

for example, "When you have jaundice, you see a conch as being yellow. The conch definitely isn't yellow, but the gall In the body makes your eye yellow, so you see white as yellow."

This process is described as "When dualistic fixation is destroyed, deluded experience falls apart, and all conceptual activity collapses. We should become completely clear and resolved about this."
