THE CIRCLE is the simplest geometric shape, with one single ’side’ or  boundary evenly enclosing space, and  no corners. You can draw it with a single sweep of a pen. As a one-sided shape, we can also describe the circle as a symbol of ONENESS, although in mathematics it is used to describe the quailty of ZERO. Ancient Greek mathematical philosophers named
.it ‘The Monad’ a word arising from the root menein, ‘to be stable’ and monas, or Oneness
 Zero and Oneness are really aspects of the same thing: nothing and everything, emptiness and
wholeness
 
 ‘You cannot conceive the many without the one…The study of the unit is among those‘ that lead the mind on and turn it to the vision of reality’    - Plato
