Doesn't the Heh/Tzaddi switch, by definition, require a breaking of an egregore built up since the teachings of the Sepher Yetzirah came into use? How is it less disruptive to correct two millennia of work based on incorrect correspondences but not to correct a hundred years of work that continued the mistake? Especially when the core purpose of Case's color/sound theory rests on visualizing the color at the same time one is intoning the note. Shouldn't we be correcting this now so that it doesn't continue another century into the future?
Based on my own experimentation, intoning the Heh of YHVH on a C-natural creates a red thoughtform which pushes me towards Aries and Mars. This is certainly in keeping with the connections between He, 5, Geburah, and the pentagram, but not in connecting it (correctly?) with Violet and The Star.
Go in all ways contrary to the world.
