When you begin to use the third eye common symbols in this world begin to suddenly have this strong spiritual appeal. Suddenly things we take for granted are no longer so simple. Wheels correspond to the Norse Odin, The Vedic Indra, the Celtic Taranis, The Jain cosmology cycle, the birth charts used by astrologers all have a common pattern. Now look at a car, driven by wheels and steered by one as well. The symbols of Hekate are keys. Keys turn on the ignition. This ignition can be metaphorically used to the power of the solar plexus which is our inner will which is driven by the third eye chakra (ajna in Sanskrit which also means command) we are in a world of symbols. We are our own symbols meanwhile studying the very symbols we make up our society of. We are the universe reflecting itself :) namaste!
