Should she or should she not have an abortion? On one hand we of Thelema state that the woman has the right to do what her Neshamah is calling her to do but on the other hand is it her duty to God (i.e. Nuit-Hadit-Horus) to allow that little zygot-soul to fulfil it's next incarnation? Crowley said that woman is the Great Mother/the Great Whore and is therefore closer to her Will than men.
See the imagery of Thelemic Devil Trump,

Now I understand that this is also spiritual metaphor but here you have a phallic symbol complete with testicles which, of course contain many spermatozoa-souls waiting in purgatory to be incarnated for when the (condom-free) man will shoot his load down the vaginal canal of the fertilization/ continuity of Nu Herself.
Then again, maybe if the zygot-soul is deprived of incarnation by the abortion clinic then that was it's destiny also? Not this time around buddy! Maybe next time. I'm sure I heard that Crowley himself was an anti-abortionist thereby but I can't find any source evidence.
