There is the mind itself. It is like a smooth lake which when struck, say by a stone, vibrates. The vibrations gather together and react on the stone, and all through the lake they will spread and be felt. The mind is like the lake; it is constantly being set in vibrations, which leave an impression on the mind; and the idea of the Ego, or personal self, the "I", is the result of these impressions. This "I" therefore is only the very rapid transmission of force and is in itself no reality.
