Only because you’re asking….
Witchcraft (and it’s an unfortunate moniker, really), is a calling, not something to be followed for its unique draw. Here are things you should know, some of which you may already:
There are many kinds of practitioners. Old world witches, those of the sea, of the woods, of healing, of covens and solitary. The best way to practice is as you see fit.
This is essentially paganism in a tiny, tiny nutshell, and others are free to expound: Respect, commune and synthesis with the natural world and its great ancient wisdom. Really nothing more. It’s tuning in to the vibration of the Universe and using that symbiosis to channel good for you and the world. A psych major might call a lot of it the law of intention and desire.
Are witches magic? I have yet to see and actual “spell” carried out. No one flies, no one sees remotely, etc. What can be done is universal bending with the breath of intention and focus, which is why the ‘accoutrements’ surrounding it. “Magic” is powerful, but it’s almost imperceptibly subtle.
Stay clear of the trappings of modern witchcraft, unless that’s your style. No one needs a wand, cape, special amulet or the darkest eyeliner available. Those are spectacle witches; the ones you see in every news story at Halloween.
Use only natural, preservative- and chemical-free items in your rituals. Nature means nature, right?
Beware of “trappings.” Crystals are not magical; they carry no energies of their own. In fact, when measured through exothermic energy, crystals are among the lowest energy-holding molecules on earth. They are also inert and chosen for medical and other technologies precisely because they react with nothing. If you find they shift your energy, focus you or simply add to beauty, don’t shy away from them. Just know there’s no magic in them. We can discuss astrology the same way, but I’m not totally convinced we’re missing some undiscovered science there. But you get the point. Create your space for you and the way you feel. Everything else will naturally follow.
Good luck in your journey. I hope you discover much and add much to the world. Let us know what you pick up a long the way.
