Controlling Elements

The idea of controlling Elements in Wicca is another misconception. I’m not going to argue here whether it’s even possible to control fire or water or air with your mind—and I don’t even know how someone would go about controlling earth (other than gardening or making mud pies). Even if this was possible, this would fall under the category of psychic abilities. While a Wiccan might believe in this stuff, or attempt to perform these tasks, it does not make doing these things part of our religion.
I do have to note here, the idea of "controlling elements" seems to me an incredible waste of time and energy. Let’s assume here for a second people who claim they have these powers can actually do what they say they do. They cause a flame to flicker or a little feather to bounce around or water to ripple at will. That’s all fine and good, but I ask… what is the spiritual lesson and benefit in this?
The amount of practice and effort that goes into what amounts to little more than a neat trick to show off with at parties is ridiculous. How does it actually help someone’s spiritual journey to waste an hour or two a day for months to learn how to make the candle flame bob up and down? It seems to me there is no actual spiritual benefit from being able to do these things—it’s just something you can use to impress yourself and your friends, like juggling 3 oranges or finding someone’s card in a deck.
Allow me to repeat myself, because I feel it’s a very important point that many Wiccans miss: the Element of Fire is not just flames, the Element of Water is not H20, and so on. Controlling a flame with your mind (even if you could) is not the same thing controlling the Element of Fire. You’re just controlling a bit of fire (small “f”). Controlling H20 is not controlling the Element of Water; it’s controlling water (small “w”). And so on.
