The Nameless Quest in The Gate of the Sanctuary from The Temple of the Holy Ghost (Collected Works, Vol I) by Aleister Crowley.

“Up rears the pillar. Quaintly shaped and hued,
It focussed all the sky and all the plain
To its own ugliness. I looked again,
And saw its magic in another mood.
A shapeless truth took image in my brain.” [via]
