Jason Louv contends that Enochian is a means to initiate into the Kabbalistic sephirah (sphere of consciousness) of Binah. The final seven Aethyrs, he argues, reveal the final to sephiroth of Chokmah and Kether, but these lock up if one has not initiated into these sephiroth. In my experience, this is absolutely true.
It is possible to request the Enochian angels show you how to initiate into these sephiroth and thus enable full visions when you scry the last seven Aethyrs. Assuming you have successfully scried through ZID, you should have begun the initiation into Binah and thus be ready for the following sephiroth. The process is long, but it is started very simply. What you do is make the normal call to the Aethyrs (“MADRIAX DSPRAF ___,” where the blank is filled in with the name of the Aethyr) and then substitute the Enochian word for the name of the sephirah (rather than the name of the Aethyr).
So, to initiate into Chokmah, you would use the word for “the secret wisdom,” ANANAEL. After making the call, follow the instructions of the angels and you will begin the initiation process. The same can be done for Kether (the highest sephiroth) as well as Ain Soph Aur and Ain Soph. I have tested this technique on three of the following four (once again, do not make this call until you have successfully scried through ZID–that itself should be challenge enough):
Chokmah (Wisdom): ANANAEL (Secret Wisdom).
Kether (Crown): MOMAO (Crown)
Ain Soph Aur (Limitless Light): MAOFFAS OLPIRT (Measureless Light)
Ain Soph (No Limit): MAOFFAS (Measureless[ness]).
