I disagree, I think there is something deep in there, although I must admit, I have no idea what it is! However, since the very essence of Thelema is Do What Thou Wilt etc. and Love is the Law, Love Under will, I suspect this has something to do with it. Perhaps whatever you do, do it not because it is your false desire, but because it is your True Will to do so. Just as the Lust card in a way embodies these mottos, I think this is connected to them.
Remember that Crowley in many cases used words that meant traditionally one thing, but he purged them of their negative connotations and gave them new and better ones. I suspect Lust is one of them; also Whore and Beast, and of course, Devil.
Can you find a specific reference?
