Thanks Belle
Thinking you're ready is one thing, actually being ready is another. As has been said above, start small, stir, mix or knead-in good intentions into food you make, cleanse your home with salt or burn sage - warning all the smudge sticks I've had have dropped little burning embers, so be careful of singe marks on light carpets and furnishings and keep a bottle of water close by. Before you do anything, learn about Protection, don't do anything without it. Practise blessings, practise divination, practise raising your awareness. Learn, learn and learn some more. Study moonphases, study the seasons, the fire festivals, the ancient places. Find out what things suit you and what don't. It's a lot like growing up, you have to find whatever you're comfortable with and go from there.
Light I've not read the books, so I may be speaking out of turn here as they could well contain knowledge, but would say from seeing the films only that if JKR actually has knowledge or has practised, she had a great awareness-raising and teaching opportunity and missed it by a mile.
The only bits I thought were decent was the make fun of your fears in order to conquer them scene, but that's basic psychology anyway.
And maybe the scene where the Weasley family go up the chimney to Diagon Alley and Harry mispronounces it as diagonally and gets lost.
Sharp lesson on knowing what you're asking for and aligning will and intention.
Mostly I watched the films chuntering negative comments. Once I took my pointy hat off and watched it as just a complete fantasy it was okay.
If you want something written for kids, but with researched real happenings in it, try Sam Osman's 'Quicksilver' and 'Serpent's Gold' are definitely worth a look. www.samhepburnbooks.com/books/quicksilver/
