Visions, apparitions, miracles, the stuff of the Internal is fleeting – transient in the extreme – virtually existent, actually non-existent. Only the External endures beyond this. But this doesn't mean that only the actual has validity, despite the fact that this is what our culture and our minds assume. For us – students of the Internal – the only real function of the External is to harbour and indicate the Internal. Traces and omens. And for us a capable body is one able to manifest energy and allow the passage of energy rather than one able to perform external work.
