Heaven and hell are within us, and all the gods are within us. This is the great realization of the Upanishads of India in the ninth Century B.C. All the gods, all the heavens, all the world, are within us. They are magnified dreams, and dreams are manifestations in image form of the energies of the body in conflict with each other. That is what myth is. Myth is a manifestation in symbolic images, in metaphorical images, of the energies of the organs of the body in conflict with each other. This organ wants this, that organ wants that. The brain is one of the organs.
