Even time is a concept. In reality we are always in the eternal present. The past is just a memory, the future just an image or thought. All our stories about past and future are only ideas, arising in the moment. Our modern culture is so tyrannized by goals, plans, and improvement schemes that we constantly live for the future. But as Aldous Huxley reminded us in his writings, "An idolatrous religion is one in which time is substituted for eternity...the idea of endless progress is the devil's work, even today demanding human sacrifice on an enormous scale. - Jack Kornfield
