A Happy New Year to you, Damien, and welcome to the Occult Underground Forums! I'll start the ball rolling and try my best to answer your questions to the best of my ability.
1. From where to start learning about the occult ? What should be the first book I should read ?
The occult covers such a wide range of topics that it can be downright intimidating to beginners. IMHO, the best way to start is to identify what subject area interests you the most and start going through the materials related to this. In our online library, the ebooks are categorized either according to area of interest or author. You can take a look at the short article we have for each area of interest or author and see what appeals to you. Once you have decided on a topic or author, you can go through the ebooks in that category at your leisure. There are no hard and fast rules regarding the pursuit of occult studies. You are free to jump from one topic to another as you please. And if you have any questions, you can post these on the forum so others can share what the know with you.
2. Is the practising of magick rituals dangerous?
Anything can be dangerous if you do not know how to go about doing it. But if you are provided with proper guidance, magick ceases to be a danger to the practitioner and becomes an exercise in creativity and an altogether positive experience.
3. Why is it importatnt to learn and practise magick/rituals?
The answer to this will vary from one practitioner to another. As far as I'm concerned, I practice magick because it gives me a better understanding of how the infinite multiverses work and, in turn, makes my manipulations much more effective.
4.What is the ultimate goal ?
I'm nowhere near being able to answer that to my own satisfaction, sorry.
Hope this helps. Feel free to chime in with your own two cents, guys.
