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

“Smitten by Beauty down I fell as dead—
So strikes the sunlight on a miner’s head.
Blind, stricken, crushed! That vast effulgence stole,
Flooded the caverns of my secret soul,
And gushed in waves of weeping. I was wed
Unto a part, and could not grasp the whole.” [via]
