The true self of man is hidden in a central core of stillness, a central vacuum of silence. This core, this vacuum occupies only a pinpoint in dimension. All around it there is ring of thoughts and desires constituting the imagined self, the ego. This ring is constantly fermenting with fresh thoughts, constantly changing with fresh desires, and alternately bubbling with joy or heaving with grief. Whereas the centre is forever at rest, the ring around it is never at rest; whereas the centre bestows peace, the ring destroys it.
