Past and future are myths. The past is just the present that has died and the future will never exists anyway, because by the time we get to it the future will have turned into the present. The present is all there is. The ever-moving, ever-changing present. And the present is fickle. It can only be caught by letting go.
We are afraid to let go, we are afraid to really live, learning to live means learning to let go. A Tragicomedy lies in our forced clinging. Hanging on is not only an exercise in futility, but it also causes us exactly the pain that we are trying so hard to avoid.
