Stories evoke a sense of wonder in our world, present a conceptual model of that world, establish a sense of right or wrong within that model, and teach individuals how to deal with major life events in the meantime.
“Mythology is not a lie, mythology is poetry, it is metaphorical. It has been well said that mythology is the penultimate truth--penultimate because the ultimate cannot be put into words. It is beyond words. Beyond images, beyond that bounding rim of the Buddhist Wheel of Becoming. Mythology pitches the mind beyond that rim, to what can be known but not told.” ― Joseph Campbell, The Power of Myth
