Before we were born we had no feeling; we were one with the universe. This is called "mind-only," or "essence of mind," or "big mind," After we are separated by birth from this oneness, as the water falling from the waterfall is separated by the wind and rocks, then we have feeling. You have difficulty because you have feeling. You attach to the feeling you have without knowing just how this kind of feeling is created. When you do not realize that you are one with the river, or one with the universe, you have fear. Whether it is separated into drops or not, water is water. Our life and death are the same thing. When we realize this fact we have no fear of death anymore, and we have no actual difficulty in our life.
