How can absence, which is not existence, have qualities like radiance and density?

I now experience my identity, which is the nature of everything, as a CLEAR LIGHT LIKE WATER, like rainbow, like reflection but Absence. I feel myself, my existence, as the immensity of presence, absolutely emptiness and infinitely deep. Yet this immensity and density feels totally light and weightless, completely devoid of any sensation. It is so empty it is total absence. It is nothing, but at the same time it is dense presence. I see everything but nothing- amazing- unique realization

How can absence, which is not existence, have qualities like radiance and density? This is absolutely paradoxical, but this is my experience
