Sometimes I can feel my heartbeat.   The minute things are what count.   The chemical makeup, the blood, the breath.   Too small to see.   Only   feel.   It goes unnoticed unless everything stops.   When you stop walking stop looking only breathing then is when you can feel the heartbeat.   Then is when it makes sense.   There are effects of the beat of a pulse, neck, the breath through the nose.   Then thoughts start to flow along with blood running through only some come to realize that we are all existing and there is some purpose of breathing and feeling your heart beat.   It is because you are real.
