Merry meet @hezron and welcome to the forum 
Oh, bella Roma! It’s been years since I had the pleasure to visiting lovely Italy and I do hope to go back someday- you live in a magickal place, Hezron! 
I am very impressed by all of your areas of study- you are researching so many wonderful aspects and types of spiritual practices, I am sure it has helped you build a strong and well-rounded personal practice of your own 
As for Aleister Crowley’s works, I’m afraid he isn’t someone whose materials I have gone into depth with myself. I know there is the Crowley Coffee Consecration and Crowley’s Pan Devotional Hymn you may be interested in (if you haven’t found them already) and perhaps @Francisco might have some more information on working with Crowley for you.
Please make yourself at home here in the forum and know that you are warmly welcome to join any discussions of interest or current Forum Activities that call to you. I’m looking forward to talking with you more soon- Blessed be, Hezron!
