"Then, by an eternal law, when the apprentice is ready, the Teacher appears. But long before this, he will have met that teacher through the personalities who have successively guided him along the path, for whenever he is ready for the next stage of his training, the necessary teacher for that stage comes to him.
Finally the apprentice must remember that in the end, there is only one master for him, the indwelling 'Being of Light,' whose persona or mask he is.
That Higher Self, itself a facet of the Eternal, one with all other facets, is the ultimate court of appeal, the True Master, and indeed the True Magician." -W.E. Butler
