Perhaps this is what Pollack means by 'gate' cards - they inspire such extensive and dramatic discussion.....LOL
I must say that I 'grew up' on Crowley, and have only recently bought and started playing with RWS, after having done a basic tarot course (which taught using RWS).
As I have mentioned elsewhere, I like to take a comparative approach to get to the bottom of card meanings. Remember both Waite and Crowley were members of the Golden Dawn, and it was required that every member develop their own Tarot deck. It was also standard practice to deliberately omit really special, secret info on published decks/books - after all, if you want to know the secrets, then join the club and go through the hard yards yourself....
So I have often wondered whether this is an example of one of those 'red herring' cards - maybe 'gate' is Pollack's own cheeky way of saying "this card holds true esoteric importance, so I'm going to tell you something else just to confuse ou and make you think for yourself..." LOL
Having said that, I am now trying to reconcile Waite's ferry scene with Crowley's 'Science'.
From the Kabbalistic POV - 6's are harmony, the sephirot that lies in the centre of the Axis Mundi (its the point where one could say "all paths lead to Tiphareth" - except that they don't... lol)
But the swords are double-edged - they can be used for good or for evil; so what would be a harmonious aspect of swords?
This is where I like the idea of the 'journey' interpretation, that somehow (although I can't quite put my hypothetical finger on it) sits well with the Crowley's idea of Science - the journey to the other shore!
There is a Buddhist tale of how a Boddhisattva (I forget which one) was sitting on a shore one day peering over at the other side. He wasn't dealing well with the side he was on, and that yonder one looked so much better. So he strolls over to a ferryman and says, "take me over there!" The ferryman says, "are you sure? coz once i take you there, i wont be able to bring you back."
So they go, and Bod is looking back going, "phew! I'm glad I'm leaving that shore!". But as they get further into the middle of the water-way, he looks bck and the shore he left doesn't look as bad as it did anymore - in fact, both shores look the same.
And so when the boat reaches the other shore, Bod steps off and now this shore doesn't look as good as it did from the other side, and (you guessed it) the one he left now looks heaps more pleasing. And the ferryman says some words of wisdom and departs, and now Bod realises that the best place was actually in the boat in the middle of the water-way, where both shores look great!
That's a rather heretical and apocryphal re-telling of that particular tale, but it does kinda get to the point of the 6 swords (no pun intended):
Perhaps its all about perspective. The unattainable objective viewpoint of Quantum physics. Perhaps if we rationally/logically (swords, mind, etc) look at something from all points of view, we find truth - and perhaps this holistic, quantum approch is the Science of Nature, the science that Crowley was trying to convey. Its not science as in test tubes and microscopes, but the science that occurs every day within the Universe. The place where magic, mysticism, measurement, and the mundane all live and cooperate in harmony (music of the spheres).
Is this not a journey of our minds? To reach the other shore to observe our issue/problem? I liked the description of that other card with the 3 swords on either side of a path leading to a cave/barrow/funeral mound (whatever it is) - that to me fits snugly with this idea.
And hey, the symbolism of the Ferryman/Charon - perhaps he is the Hierophant, or maybe the Hermit? Perhaps later on in the Buddhist tale, the ferryman comes back when the Boddhisattva has his realisation, and they go off boating together to lots of different shores....maybe get in a spot of fishing while they're at it.... LOL
How do y'all feel about that? I'd love some feedback.....
