The world is reversed inside our retina, you can gaze at a mirror in a deep meditative state, and you will be may be shocked about what you’ll see. The higher spiritual masters have always known that what meet between the eyes can be hidden in the corner of those same eyes. the limit between matter and anti-matter, between what is reversed and what is normal, all this the duality ends, and the certitude/belief/absolute proof, can be reached with you OWN SUBJECTIVE spiritual journey. Nobody can be you, so you bette KNOW THY SELF
