I would tend to agree with how individual magick is. Personally im pretty new to structured occultism ( last 2 years or so) so having a form of structure is helpful, otherwise my low attention span has me researching Egyptian funeral texts one minute and the next Cattle mutilations haha. How was your path starting with magick? I know its a lifelong process but I tend to be impatient so was there anything you can think back that jumpstarted practical development?
I have times where I go from one subject to the next quickly too. Most of the time because of a lack of energy and thus of focus. I believe many magickal experiences are deeply connected to how you decide to look at what you do. So, instead of feeling bad and seeing all my (already low) energy scattered, I try to draw all the stuff together to a broader picture. So I ask myself: what has the cattle mutilation to do with the Egyptian funeral and how does this all apply to my actual magickal work? This often leads to astonishing insights and perspectives on my magickal doing. Things fall into places and missing links suddenly show up.
In this example, I would look up how the mummification has been done in old Egypt. I remember that they took away the brain and all guts. Isn't this a kind of mutilation? What did they do with the guts? What did it mean to them back then and what does it mean to me and my magick today? Do I have an aspect which feels mutilated? Can I maybe heal it in connection with what I found out about old Egypt? Or is my magickal work somehow mutilated, is something important and natural missing? And so on ...
My path starting with magick? Hell, yes, it was a long road. I always seeked for contact to the spiritual world. When I was young, it was not just praying to god which satisfied me. I wanted to communicate with god, really communicate (which disappointingly didn't happen). I tried religion and mysticism (Yoga), which harshly pulled me away from my goal. It's too lengthy to tell the whole story, but in the end my dreams and my intense and very intimate feeling of my true inner core helped me to find my way.
So I would say, the best thing is to make contact to your inner magickal core, your inner connection to the magickal/spiritual realms, which some call the HGA or the Holy Daimon or whatever. It doesn't necessarily have to be a magickal entitiy , it also can be an energy, a certain flow, a magickal place, a magickal feeling, intuition or instinct. - For me it was a place deep in earth, directly connected to my soul, for a long time, before I turned towards personification into a kind of HGA (I am not working with angels, so I actually don't call my most intimate magickal friends angels). And yes, my dreams accompanied me my whole life and taught and still teach me a lot.
In my experience, the really big advantage in finding this contact or connection is, that you have a deep inner knowing reference on whatever you do. You better understand what is right for you and what not, where to turn next, how to find your way through the jungle of magick and so on.
I don't know, where the Quareia course leads in the end, but as far as I understand, it strongly focusses on inner work and vision. I think, it provides a bunch of really helpful tools to stand on your own feet quickly. (Although when rushing through the guide book a bit, I saw some things I would never recommend to anybody. But in the end everyone has to find his own approach and decide on what he feels is right or wrong.)
