Just returned from a yoga class with a sub, a young guy who was a good teacher, though there were a few things lacking. For the most part, he is quite good though. He is the student of a yoga teacher I had a workshop with perhaps 6 months ago. She teaches up in the Valley, and is one of the founders of the Iyengar Institute. She was extremely helpful to me, spotting my hip problem and beginning to work on it immediately.
I realized this morning that what Bob always says is very true, not only for yoga, but for life in general. If one acts out of fear, to keep something from happening that one fears will occur, that thing will almost surely happen. Bob always says this when we are in back bends, draped over the backless folding chair backwards with our chests wide open, supremely vulnerable, if we choose to view it this way. If we grab at the folding chair's seat to prevent the chair from folding up on us, it will fold up, pinching the arms in a supremely uncomfortable grip. I have done this, one too many times now. This is what I believe happened to me at the college.
