ΚΕΦΑΛΗ ΚΓ (23)
What man is at ease in his Inn?
Wide is the world and cold.
Thou hast become an in-itiate.
But thou canst not get out by the way thou camest
in. The Way out is THE WAY.
For OUT is Love and Wisdom and Power.
If thou has T already, first get UT.
And so at last get OUT.
~Chapter 23, The Book of Lies by Aleister Crowley
At least, this is how I illustrate it using the Tabula Mundi tarot cards. At one point, T clearly has to be Teth/Lust, yet also, T is the Tau/Universe.
