There is a quote from Crowley, (and I'm assuming I can quote him here as he is quoted in the course lessons) from the book Liber Al Vel Legis which says "For pure will, unassuaged of purpose, delivered from the lust of result, is every way perfect." (AL I:44)
For the Practitioner of Magick there must be an understanding that one may desire for a thing to come about and perform a Ritual to aid in making this happen, that once the ritual is done, once the force of your will has been released into the world it is best to forget about it.
wipe it from the mind with no hope of gain, with no lust for result so that you don't inadvertently by thought, word, or deed tamper or cancel completely the work which you hoped to achieve.
This is simply my understanding of this and your post compelled me to share my thoughts on this subject
thank you
