As far as symbols go, the cross also predates Christianity and is found in one form or another in cultures around the world. Magicians have used the cross for centuries to stand for complete balance of all aspects of our psyche. When we’re in perfect balance, forces outside of us—human or otherwise—will have a much more difficult time implanting suggestions into our mind stream or otherwise influencing our energy field.
