Every time we look at the world around us, part of the visible reality is a hallucination. Despite the fact that our body is tripled in an incredibly complex way, there is a small defect in the human structure - blind spots in the eyes, an area on the retina of the eye that is not sensitive to light, a small black spot through which we always see emptiness. If every time we look into the world we physically cannot see everything that is in it, every time we miss something, then perhaps we can just relax and accept the fact that nature is not given to us to see and count everything and part of the world will remain for us blind spot.
