I want to know from first hand experience what all Hatha Yoga (common yoga, which involves many physical stretch poses, as opposed to the more meditation oriented yogas like Raja Yoga) really does and how effectively it does it. I was into it for a little while in the early 90's, but I might not have really given it a chance to do much. It was a lot of stretching while deeply breathing. Stretching can make you feel good, and so can deep breathing. After a yoga workout, I would feel pretty good, like I had just experienced light exercise and deep breathing and had stretched and relaxed my muscles, but it didn't blow me away enough for me to stay with it. There are some pretty extreme claims made about Hatha Yoga's long term benefits, such as balanced endocrine system and enlightenment and so forth. I am curious about how much truth there is in that and if anybody can tell me they have gone far in that direction. If you feel like Hatha Yoga has done a lot for you, please tell me what you think it does. So many people have gotten so dedicated to it that I suspect there must be something major to it. What is it? Thanks.
