(To get from Kether to Tiphareth)
'As the only middle-pillar path that spans the Abyss,' writes Lon Milo DuQuette, 'the position of the High Priestess on the Tree of Life is unique. She links the ultimate Father of Kether to the Son of Tiphareth and, in so doing, joins the supernal triad to the rest of the tree. The Abyss she traverses is, quite literally, the desert of the soul, and like the desert camel, she is the only vehicle capable of crossing that terrible waste land.'
Aleister Crowley says, 'In this card is the one link between the archetypal and formative worlds.' But, one wonders, what about the 'as above, so below' powers of the Magician? Oh well.
