- A barrier of some kind. Loneliness or separateness. Emptiness. Nothingness. A trick. Only a picture of reality. Not what it appears to be. The surface of a mirror. The direction of past. The direction of outside yourself. The way back to yourself is to see your reflection in the mirror. To challenge your perceptions. To revise your interpretation. You leave nothing behind, only reconnect with that which was always there and waiting for your return.
