The evolutionary path of human consciousness may be simplified into these main categories. On a physical level the human spine requires electrical connection that mainly comes from the earth itself. This connection keeps us on the physical plane. Meditate on the connection to the center of earth from our pranic tube, allowing the flow (current) to move in, through and around our auric field. From this connection we discover the earths connection with the sun. This conscious connection then may expand to the stars and other planets.
