The coolest part and confusing part about magick is it is a very personal for each practitioner. I am new here too but yet if someone posts a ritual they did or spell that they “made up” I have not heard one person say that is wrong. The information in the books is vital don’t get me wrong, but you can find your own way of doing things. The books and information show you the effects each component like, mantra, meditation, sigil, runes, elements like stones or metals have. You may utilize them as you see fit. Of course trial and error can end in bad error. So these grimoires and this community serves as a great data base of what does not work well together through others error.
I make shift an altar every time, it is simply a surface to perform. Welcome and take a deep breath there is a lot of info. But do not think you need to go online and buy a surplus of stuff. Sure you can it is convenient and you may want to make say a book of shadows ornate or have a nice pendulum etc. Many rituals can be done empty handed the biggest thing is your vindictiveness.
