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

“Sleep there, nor know me gone: sleep there
And never wake, although God’s breath
Catch thee at midmost of the prayer
Of sleep—that so dream turns to death!
Pass, be no more! The beckoning dawn
Woos the white ocean: I must go
Wither my soul’s desire is drawn.
Whither? I know not. Even so.” [via]
