Lukewarm take: If you want to get good at practical sorcery, you're probably going to have to do a lot of magic you don't need to do, just for the sake of practice
I do not like or support the idea that ~all~ witches are supposed to be spiritual bodybuilders who are ~supposed~ to do daily training drills.
But some people really would like to really practice certain skills related to witchcraft (as in, habitually engage with a skill for the purpose of improvement).
I'm really into sorcery, and every time I bring up the idea that to get good at it you should practice it, I feel like someone always ends up saying, "but I don't need anything."
IMO there is a very unhelpful vibe when it comes to ""practice discourse"" where it is assumed that if you don't need something, then it isn't useful to practice it.
Case in point, cleansing!
A lot of people say that you don't really need to cleanse things, not even spiritual tools; that it's a handy skill to have if you need it, but it's not necessary.
My point isn't whether or not you really need to cleanse things.
My point is the practice that cleansing can bring!
Cleanse a hundred objects, and you have a hundred more interactions with magic under your belt.
Depending on the method of cleansing you're doing, you've enchanted a hundred dishes of salt water, a hundred sticks of incense, said a hundred charms.
You've engaged your willpower and magical mind a hundred times.
You have a hundred more experiences with how working with that energy, or that correspondence, or that charm affects you; how it leaves you feeling; how it leaves the object feeling.
Imagine how effective a charm might begin to be if you use it a hundred times. Imagine the experience you might gain using ten different cleansing methods ten times each.
You've got a lot more experience with objects before and after they've been worked over.
A person who does a hundred cleansings may not begin to develop an innate sense for the spiritual grime that can accumulate in the world around us, but I imagine they'd be a lot more likely to than someone who doesn't cleanse at all.
The thing with magic is that (IMO) you can never just practice one thing at a time. If you practice cleansing, you may also be practicing enchantment, energy work, psychism, petitioning, and so forth (again, depending on your methods).
And when the time comes to cast, idk, a prosperity spell, I would put my money on a guy who has only been cleansing because he had nothing better to do, than someone who hasn't been practicing any magic at all in the same timespan.
It goes for anything. A hundred energized little rocks to change the mood of a room. A hundred bits of string to tie up an annoyance.
Maybe you don't NEED an annoyance tied up.
But if you WANT to practice magic, then what does it matter what the magic is for?
