[Treatise:] Because it exists in contrast to form ... the mark of empty space.
[Exposition:] This is the explanation. In contrast to obstructing form, in places of unobstructed light and dark one says there is empty space. However, this unobstructed mark of light and dark is form of the realm of emptiness, a mark visible to the eye; it merely draws forth the thought arising and ceasing from moment to moment. "Because all form dharmas..." and below reveals absence in terms of principle. Empty space was originally established in contrast to form; since the essence of form is itself non-existent, how could there be the mark of empty tranquility?
