Imagine yourself entering the presence of a mighty emperor. You are overwhelmed with awe at his power, and with a sense of your own insignificance. Your entire attention is absorbed by the emperor’s greatness, so you are utterly unaware of his physical presence and of the other people around him. When you leave his presence, people ask you about the other people, about his physical appearance, and about your own experience of being in his presence. But you are unable to answer.
This is a parable for losing the sense of self.
