Apologies if I repeat myself from other earlier posts in what follows.
Part of the reason I developed this, I suppose, quite personal way of connecting the Tree and the Tarot stems from some studies I was doing of both the Kabalah and the Tarot independently of one another. Though I had come across, and had already worked, some Golden Dawn associations, to me it was (at the time) clear that these contradicted what I still consider to be the foundational text for Kabalah: the Sefer Yetzirah - which states that the letters are placed in either a circle, a sphere, or in concentric circles (depending on the version and its translation). In each case, certainly not upon connections between sefirot.
It was also clear to me that Tarot cards which clearly depict Hebrew letter correlations (outside the quite 'obvious' similarity of outline between Alef and the Magician and Lamed and the Hanged Man) were added, and that, in many cases, the cards were actually modified ('rectified', according to its creators) to allow for presumed correlations. Again, the foundational deck(s !) remains, for me the Marseilles - whether or not it originates in Marseilles (which is another question).
Meditating and reflecting on these independently, a number of independent insights (or so I take them to be, though others may see them as either delusional or oversights) were able to later merge. On the one hand, there was the insight (mid-80s, if I recall) that the cards of the Major Arcana can be pictorially paired into significant units, using the Roman numerals as their indicator. Here, it also seemed that X/XX formed somewhat a different type of pairing. As for the ascent upon the Tree, what was of significance was that, as Living beings, we partake of the Tree of Life (we are in some ways, Adm Kadmon), and thus inevitably must taste of the Leaves of Knowledge (Da'at). Da'at is thus not part of the Tree of Life, but arises as a consequence of our individual incarnation. Further, therein (in Da'at, that is) were the leaves of the Tree of Knowledge: the Letters.
So, it seemed clear to me that the ascent upon the Tree also lead to an exact equivalent (quasi-gnostic) path as that depicted indepentently by the paired Major Arcana - even the X/XX pair, standing 'outside' the series, could easily be placed (in Da'at).
...and so my positioning - which remains just that - unless others decide that, upon reflection, it becomes meaningful for them, at which stage a shared insight emerges (rather than 'mine which others have adopted').
As to the interconnecting paths, I do also use these, but again not in the popular Kircher pattern, but rather as edges upon a 3-D version of the Tree - though this is probably the subject of another thread.
