Why A Dragon?
Dragons are known through out the world in virtually all climates, cultures, and eras as beings with horns, claws, breath of fire, great size (some small), wondrous wings (some wing-less), and marvelous colors. These serpentine creatures forever populate our myths, legends, novels, and movies. Dragons are strong, fierce, powerful, and persuasive. As such, they are creatures of magic and power. In some Western, Christian-oriented cultures the magic and power of dragons is a masculine symbol of destruction to be slain. How ironic that it is a man’s (St. George’s) job to slay the dragons before it devours all that is feminine. In other cultures, dragons are positive symbols: Chinese dragons are symbols of good fortune. In the Aztec, Olmec, Mayan world, their dragon—Quetzalcoatl—symbolizes sustenance and re-birth. In the old Slavic world, some dragons—Zmaj —were friends of humans while others—Azdaja—were friends of witches and such. When they would fight great storms would occur.
Dragons are creation of the human psyche representing the passion, fierceness, and magic of humankind that have been repressed in the name of the rationality and civilization that are supposed to bring us peace and safety. Unfortunately, as we deny our passions, our fierceness, and our magicality, we also deny ourselves possibility: the possibility of creating humankind, our societies, communities, organizations, and families to be as healthy, productive, and engaging as we would like them to be.
The Center for Human Systems (in its vast and unbiased wisdom) is clear that dragons are good or evil depending on how we are collectively treating ourselves. When we treat ourselves and others well with support, compassion, even fun, we are creatures of fertility and good fortune. As such, they are not only creatures of power and magic, but also creatures or possibility. When we treat our collective ourselves poorly as if some must lose while others win, the price we pay is high in discord and ennui from which wars, environmental destruction and poverty result. It is the dragon of our collective selves that give us the ability to see ourselves as human systems that we can take charge of rather than they being in charge of us.
