Ever read Hyperion? The 4th book spends much time describing a very similar phenomenon its now how I picture the trasposition of soul. Bakker's Outside being Simmons' Void Which Binds
Basically, the 'Outside' is everywhere at once. This MG cant lets you 'move' from one 'place' to the next without traversing the distance since you are going through the "spaceless" outside.
That was abstract and confusing. You explained very well, and certainly much better than me.
I was wondering about the cants of calling though, not the cant of Transposing.
Lol.
Cants of Calling: ... Though the metaphysics of these Cants is only loosely understood, all long-distance Cants of Calling seem to turn on the so-called Here Hypothesis. One can call only to slumbering souls (because they remain open to the Outside) and only to those residing somewhere the Caller has been. The idea is that the "Here" of the Caller can only reach a "There," or other location, that has been a "Here" sometime in the past.
But surely, you know this, Father
?
I just think it strange that all the schools are able to do this, and yet the gnosis is so much more powerful. Maybe the anagogic schools "calling" cants are like Skype with slow internet connection, where the gnosis calling is a full HD video feed without lag

. The only thing better than that would be actually being there talking... Oh...
