To be carried to the Grail Castle is to cross into the supra-personal domain and to enter the Greater Mysteries. The obtaining of the Grail signifies the supreme unconditioned state and the completion of the Greater Mysteries. In the Arthurian cycle this attainment is rarely immediate. Parzival must return again and again before he is able to behold the Grail in truth, just as Dante must pass through the planetary spheres before reaching the Empyrean. The knight who finally wins the Grail becomes the visible bearer of a kingship whose true seat lies beyond the world. He stands at the head of an initiatic order whose authentic center is no longer earthly. His task is to found or restore a kingdom below that reflects the kingdom above, binding the visible realm to the invisible center. From this perspective, the meaning of the Grail becomes clear. It is the spiritual key to the formation of medieval kingship and, ultimately, to the idea of Empire itself.” -
“For a certain period of time it seemed that the Ghibelline Middle Ages approximated this kingdom to a great degree. This epoch appeared to offer sufficient conditions for the "kingdom of the Grail" to turn from occult into manifest, affirming itself as a reality that is simultaneously inner and outer, in a unity of the spiritual authority and of the temporal power, just as it was in the beginning. In this way it can be said that the regality of the Grail constituted the apex of the medieval imperial myth and the highest profession of faith of the great Ghibelline movement.” - Julius Evola, Mystery of the Grail
