The cycle in which consciousness invests itself into illusion and the experience of what it is not is called the involutionary cycle. Once we are full in the experience of what we are not through the illusion of separation through pretense ... once we have created enough conflict and experienced enough resultant suffering then it could be said that we are full in the experience of what we are not. We're pretty through when we've explored every nook and cranny of what it is to be that which we are not. Once we have reached that extreme, the opposite polarity actualizes. That opposite polarity is the evolutionary cycle and the point where we change from the dominance of involution, illusion, to the progressive dominance of truth evolution is the point of awakening.
