Well the thing is that you first have to learn all the occult correspondences. That is how all things correspond to each other and that is a laborious process. You can do this on your own to a degree. There are a few organized systems. One is the Golden Dawn. They are great. The book "The Golden Dawn" by Israel Regardie is excellent. That would be a good point to start. He was Crowley's top student and makes things easier than Crowley. You have to completely restructure your thinking and mind and that takes a lot of work and study.
I HIGHLY recommend the 777 deck for learning. They are hand made by a great guy and he charges little for them. He just wants to help people learn. This is a learning deck to teach occult relationships. "Correspondences"
Yeah I would study Golden Dawn. I would spend a hell of a lot of time at first on this website and get his cards. You have to restructure the subconscious and it takes major work. If you want to know anything I would try and answer. I will do it here for everyone's benefit in the event that someone else too is meant to have the knowledge.
