"For a long time the new Initiate will not be able to understand all that this union implies, and he must penetrate far into the sanctuaries before he can realize how close is the link, and how great is that consciousness of the King himself, which all Brothers to a certain extent share with him. It is incomprehensible and inexpressible down here; metaphysical and subtle it is beyond words, but nevertheless a glorious reality, real to such an extent that when we begin to grasp it everything else seems unreal."
