The article would be nice if it were called something like the "The Cost of a Fantasy Yoga Year." I would love to do many of the things listed in this article. I have not because I cannot afford such things. That doesn't make my yoga any less "real." I would say that it makes it more so.
I have had very inexpensive yoga years. Last year, when I lived in Kentucky, I maybe spent $45 on yoga. I had a home practice and a yoga journal subscription and would pay for classes only when I traveled. The year that my husband went to Albania, I was able to practice yoga for free by offering to do work study at the yoga studio. If yoga costs a lot, it's because people choose to make it expensive. It doesn't have to be.
It makes me sad when I hear people say that they're uncomfortable practicing because it seems like everyone at a studio wears expensive yoga clothes. Maybe one of the first steps to freedom through yoga, is to stop worrying about what everyone else is doing. I like expensive yoga clothes, sure, but I don't need them for my practice. And, on principle, I like them less these days as they are moving more and more jobs overseas while increasing their prices. But that's perhaps for another post.
