It is clinging that causes suffering.  It is that simple.  Reality is what is before you, not in the past, not in the future.  Deal with what is in front of you right now, and we are not speaking of predictions.  Are you breathing right here, right now?  What is breathing you?  Be with that, here and now, and release your clinging grip.  What an opportunity to practice presence.  The kingdom of God is within.  Focusing on deep breathing will take you there and make you aware of the very human thoughts and behaviors at the root of suffering.  You are so very loved.
