Thanks for posting this, Forest. I especially like this quote from the article:
"Clearly, in cases where yoga does not offer significant relief from physical disease, it can still offer some measure of relief from suffering. In this sense, yoga can provide a different way of looking at pain and suffering, which in itself can potentially alleviate some suffering. The basic realisation that “I” am not my body, or my thoughts, or my sensations of pain, is itself healing or liberative from a certain kind of existential suffering."
I wrote a post about a month ago about my experience with pain while doing Bikram Yoga, which is similar to this quote.
