Dream
Are you awake? We dont really know if we are asleep or not. In general, any person who perceives only our material world is considered to be asleep. We perceive everything in our world only through comparison: light—dark, sweet—bitter. Everything is felt through comparison and contrast; a clash of two different sensations. We feel this clash at their point of intersection, and we are unable to sense one opposite without the other.
During the time of development when we perceive no world other than our own, we simply cannot tell if we actually exist or if we are in a dormant condition. Are we alive or asleep?
Only when we actually wake up, will we then realize that we were asleep all along. For this awakening, we need to reach a new level of feeling the world. We need to enter a new dimension, and then by comparing the two dimensions, we will realize that neither is perfect on its own. Only in the contrast and unification between these two worlds will we find our true existence.
