To imagine is one thing, and to perceive what is is another, but both are binding. It is easy to perceive what is, but to be free of it is another matter; for perception is clouded with judgment, with comparison, with desire. To perceive without the interference of the censor is arduous. Imagination builds the image of the self, and thought then functions within its shadows. From this self-concept grows the conflict between what is and what should be, the conflict in duality. Perception of the fact and idea about the fact, are two entirely different states, and only a mind that is not bound by opinion, by comparative values, is capable of perceiving what is true.
