One might think that this is all, and that after death there will be nothing left for the ordinary person who has thought of himself as this body, so tall, so broad, so heavy, so many years old; that when the physical body is gone all is gone. But it is not so; when the body is gone the mind remains, the finer part of man's self, composed of vibrations. The elements exist in the vibrations as well as in the atoms, otherwise a person who is angry would not get red and hot. In dreams, when the body is asleep, we see ourselves walking, speaking, acting, in certain surroundings with certain people. It is only by contrast with the waking condition that we call it a dream. This self still exists after the body is gone, the exact counterpart of what we are now, not of what we were when we were five years old, or ten years old, but of what we are now.
