Bardon, in his third book, says that Divine Providence has only allowed him to reveal three of the Tarot cards Arcanum. but he wishes that he could at least do two more. Since Bardon is gone, maybe his students know what he was refering to, but I haven't read anything to that exact effect. The question is, at that level (after mastering the thrid Tarot secrets) does one no longer need any instruction and instead receives instruction from the Guardian Genius? or from other Beings? or from Divine Providence? And if that's the case, then someone should at least know what the topic of those Tarot cards are. So why hasn't someone continued Bardon's work, presuming that Divine Providence allowed it? For Bardon saw it as being beneficial to higher adepts that had progressed that far, so it must have been worth the effort to do so.
