This is where I find a personal obstacle - dealing with diabetes in conjunction with so much exercise. I don't know what's normal fatigue, and what is pushing too far for me personally.
More than anything, I am learning that just because I do yoga (almost) every day, and just because I've been doing it for years, I'm not automatically ready for every pose, or even for the final stages of some of the more basic poses. At least not when I'm actually in right alignment!
Meditation was excellent though. I couldn't feel the lightness of the body in my back during class, but that lightness was tangible while seated in meditation. Tangible and wonderful! Our meditation practice was one where we guided the breath in one nostril, while visualizing it, and then exhaled out the opposite nostril, but without the hand mudra actually closing one nostril off.
At the beginning of this instructor program, I worried about the meditation portions, since it's not something I've enjoyed before. But now I'm finding that I look forward to it every class!
