s 17 Twilight
Twilight is the crack between the worlds. This is not a metaphorical crack but a literal one formed by aeons of pneuminous activity which perceives this vector of alteration (the changing air and light) as a gateway. The perception of Twilight as the weird space it is has made it into exactly that. Twilight is a node of opening into something else.
Twilight (s) is a circuit node with Passion (j) preceding it and Freedom (l) following it. Sol (v) is the feeder node for Twilight.
Other accretive aspects of the node are: Hebrew letter: Peh, Tarot: Tower, Blackbird, Blackthorn, Threonine, Choescystonin, Calcitonin, Choline, Transposition (logic), Binomial theorum.
