...that seems most accurate to me is: "Enlightenment is the realization that the one seeking enlightenment does not exist and has never existed. Personal selfhood is seen to be an idea, only. The realization, itself, has nothing to do with understanding, and does not occur over a period of time. It is instantaneous. It is a collapse of the thought structure that supported a sense of selfhood and separateness. Until that very moment, the body/mind thought of itself as an entity. Suddenly, that thought is totally seen through, and it literally evaporates.
