Firstly, a terminology lesson: a crutch is usually a tool to help someone perform a task, it could also technically be a method or technique, but it I’m going to talk more along the lines of the first definition.
An example could be how if someone injures a leg, to their foot, they’ll need a cast and a crutch. At some point and time, the person will start using crutches to help them walk, as they can’t fully do it on their own without harming themselves.
Another example could be someone using something to enhance skills or ability, like steroids would be a drug that enhances strength. See how those two work? It either helps perform a task, or helps enhance an ability.
In occult terms, a crutch could be like crystals, incense, candles, almost anything that helps ease the way to do a task. In this instance, anything that is required to do that, like in order to do a reading with runes, the reading requires runes. So that would not be a crutch.
Now, I’ve always had an iffy attitude towards crutches. I do not like inadequate feeling relying on methods like that makes me feel. But that does not mean I disapprove of it (as if my disapproval would impact much anyhow) I can respect it still. I like magick, and I like all of that. I better I’ve spent a small portion of my life devoted to learning about it. To me if it is a way, and someone uses that way, I’m less inclined to down talk it.
I just don’t want to use crutches, I have the mindset that I won’t always have what I’m using as a crutch. And I don’t like to feel overly dependent on something, even though there are things I am dependant of.
An example can be of an RPG game, because I like those type of games, and can help with this the character that the player plays as will have base stats, while there can be ways to increase the players stats, or the tools the player uses throughout the game.
Regardless of my viewpoint I do see how crutches can be useful. As they can aid so many practices and have so many other uses.
But, holding onto this viewpoint is highly unrealistic, as no one can get through all by themselves without using anything, as in a sense tools are crutches too.
