Ego's Fear of Space

“Q: Why do you think that people are so protective of their egos? Why is it so hard to let go of one’s ego? A: People are afraid of the emptiness of space, or the absence of company, the absence of a shadow. It could be a terrifying experience to have no one to relate to, nothing to relate with. The idea of it can be extremely frightening, though not the real experience. It is generally a fear of space, a fear that we will not be able to anchor ourselves to any solid ground, that we will lose our identity as a fixed and solid and definite thing. This could be very threatening.”
