When we look at a snow capped peak, we can distinguish its age.  Maybe, it has as many years, or even more than man on earth.  But all this in the  infinite wisdom of Spirit is as blinking. The knowledge of man, no matter how much, will always be as a grain of sand in front of a mountain. That's why, spirituality is not a path to increase information but is the art of living one moment at a time. And this may seem superficial but when we are alert and awaken, we don't consider reality, beyond ourselves, but we are in that precise moment, unconditional beings integrated into an universal breath without frontiers in the universe. That instant is eternity and in truth is everything that we have : An unconditional present. For the mind: This is to contemplate in a serene way.  For the body, this is harmony.  And for the spirit, this is to flow.
