The Rosicrucians, Freemasons, Golden Dawn and other occult societies use allegory and poetry to hide sublime truth. To hide sublime truth from the unready and the unworthy. Those who understand will understand. Those who do not, confused.

And with that in mind, a quote from Crowley.
“Beautiful art thou, O Babylon, and desirable, for thou hast given thyself to everything that liveth, and thy weakness hath subdued their strength. For in that union thou didst understand. Therefore art thou called Understanding…”
