The material world of the waking state is symbolized by the large lower
curve. The deep sleep state is represented by the upper left curve. The
dream state, lying between the waking state below and the deep sleep
state above, emanates from the confluence of the two. The point and
semicircle are separate from the rest and rule the whole. The point
represents the turiya state of absolute consciousness. The open
semicircle is symbolic of the infinite and the fact that the meaning of
the point can not be grasped if one limits oneself to finite thinking.
