The Automobile Metaphor is a metaphor used to illustrate the relationship between Spiritual Ego as driver, and Physical Unit as vehicle. The automobile metaphor emphases the fact that the vehicle belongs to Self. In order to be considered a fully functioning vessel, the physical unit must be responsive to and aligned with the nature and intent of the higher Self.
