Hi Debra,
Indeed it could all be bs!
I concede there aren't any people illustrated above the wall. It's just my theory of what the
symbolism represents based on what I know about Crowley, i.e., the strong influence of Qabala on him and the hierarchical nature of the Crowleyan system. There's also this comment:
"The green mound represents the fertile earth, its shape, so to speak, aspiring to the heavens. But around the top of the mound is a wall, which indicates that the aspiration of the new Aeon does not mean the absence of control."
(Love is the law,
love under will.) "Control" can indicate a couple of things. It could indicate those above the wall who represent the "will" that governs the "love" (complete freedom) below. Or it could indicate that though many may aspire to the "heavens," only a chosen few are permitted to enter, the wall symbolizing the control mechanism which accomplishes this.
The wings on the children are symbolic. In the description, Crowley mentions that the children represent "complete freedom." The wings symbolize this.
