The heart of the confusion is that man has a sense of self which seems to him to be continuous and solid. When a though or emotion or even occurs, there is a sense of someone being conscious of what is happening. You sense that you are reading these words. This sense of self is actually a transitory, discontinuous event, which in our confusion seems to be quite solid and continuous. Since we take our confused view as being real, we struggle to maintain and enhance this solid self. We try to feed it pleasures and shield it from pain. Experience continually threatens to reveal our transitoriness to us, so we continually struggle to cover up any possibility of discovering our real condition. "But," we might ask, "if our real condition is an awakened state, why are we so busy trying to avoid becoming aware of it?" It is because we have become so absorbed in our confused view of the world, that we consider it real, the only possible world. This struggle to maintain the sense of a solid, continuous self is the action of ego. Ego, however, is only partially successful in shielding us from pain. It is the dissatisfaction which accompanies ego's struggle that inspires us to examine what we are doing. Since there are always gaps in our self-consciousness, some insight is possible.
