We have built a marvelous world around us. Dickens and Shakespeare endeavored to write. Vincent Von Gogh and John Quin did painting. Einstein and Stephen Hawking solved a part of scientific mystery. Beatles and Pink Floyd brought music in our life. Yet it is hard to believe at times that this world really exist.
This world mostly exist in our minds and the only time we perceive its physical aspects when we are in pain. We carry another several worlds in our brain. The ones with where we are crazy rich party animals. And their are those who have no clue of world above ours. They might be right.
