Underneath our ordinary lives, underneath all the talking we do, all the moving we do, all the thoughts in our minds, there's a fundamental groundlessness. It's there bubbling along all the time. We experience it as restlessness and edginess. We experience it as fear. It motivates passion, aggression, ignorance, jealousy, and pride, but we never get down to the essence of it.
