Early human beings the world over wondered at the sources of power that fueled volcanoes, thunderstorms, tidal waves, and earthquakes. They celebrated and venerated the rhythm of the seasons, the procession of heavenly bodies in the night sky, and the daily miracle of the sunrise. They questioned how it might all have started. The collective unconscious of many civilizations has told stories of angry gods; dying and renewing gods; fertility goddesses; deities; demons; and spirits of fire, earth, and water.
