Excerpt About Subtle Experience
It is possible to see that space is present all the time, and that it underlies and inheres in any object that we perceive. So space becomes the inherent emptiness, the inherent openness in experience. That is why in some of the traditions, as that of Dzogchen, Being is described as having emptiness as its essence. Experientially, as we penetrate the representations through which we perceive, we discover that Being is presence whose essence is spaciousness. Our perception and understanding of spaciousness can go through degrees of refinement, which are experienced as the levels of space, until we recognize it with complete objectivity, which is possible when there are no obscurations in our experience of reality. At this subtlety of perception space and presence are so indistinguishable that experience becomes paradoxical. It is both being and nonbeing, both presence and absence, but not exactly, because even being and nonbeing are categories not free from representations. This is the dimension of the mystery of our Being.
