From this standpoint, we are able to find a thread to conduct us through the labyrinth of Greek myths. Let us consider the legend of Heracles. The twelve labours imposed upon Heracles appear in a higher light when we remember that before the last and most difficult one, he is initiated into the Eleusinian mysteries. He is commissioned by King Eurystheus of Mycenae to bring the hell-hound Cerberus from the infernal regions and take it back there again. In order to undertake the descent into hell, Heracles had to be initiated. The Mysteries conducted man through the death of perishable things, therefore into the nether-world, and by initiation they rescued his eternal part from perishing. As a Mystic, he could vanquish death. Heracles having become a Mystic overcomes the dangers of the nether-world. This justifies us in interpreting his other ordeals as stages in the inner development of the soul. He overcomes the Nemaean lion and brings him to Mycenae. This means that he becomes master of purely physical force in man; he tames it. Afterwards he slays the nine-headed Hydra. He overcomes it with firebrands and dips his arrows in its gall, so that they become deadly. This means that he overcomes lower knowledge, that which comes through the senses. He does this through the fire of the spirit, and from what he has gained through the lower knowledge, he draws the power to look at lower things in the light which belongs to spiritual sight. Heracles captures the hind of Artemis, goddess of hunting: everything which free nature offers to the human soul, Heracles conquers and subdues. The other labours may be interpreted in the same way. We cannot here trace out every detail, and only wish to describe how the general sense of the myth points to inner development.
