The Angel Fire Degree requires the Pathfinder Degree as part of its substructure, just as the Runic Degree requires Medicine Powers as its actual grounding course. I would only attune someone to the Advanced Golden Ray Degree, if I was secure in my knowledge of their Foundation. In the same way I have taken ‘Masters’ from other lineages back to do their Foundation First Degree with me, because I needed to re-attune their totality to a higher vibration. At the same time as teaching them the proper conduct of handling Sacred Energy, in a safe way, from scratch.
