Spirituality and Perception
Viewed backward, the meditator is watching the de-construction or decomposition of "self" and "object" into their elementary components, processes or events. Insight meditation "reverses the way the world appears".
Buddhism did not deny the reality of the environing world, but it believed that the world as given in the ordinary reflective consciousness was a product of the concepts, hopes, fears, and desires of man.
