Just now I read a posting at http://groundingthruthesitbones.blogspot.com/2007/05/opening-comments.html regarding the Yoga Journal Conference in Lake Geneva. When you read the post, you'll see that the one thing that all Yogis agree on is to disagree. Well, it might not be that bad, but it's pretty close.
Here is the comment that I left regarding the issue of "expert" Yogis having such differing opinions:
Somehow the different opinions from the "expert" Yogis has always given me a sense of comfort. The first time I was exposed to these differences, I was scared. My background was math and engineering--there must be a "right" answer. What I learned, was that if there was a "right" answer, then no one knew it.
Over time, I came to find freedom in these differences and realized that what feels "right" and good for me is what's right for me--not necessarily for someone else.
On different days, different moods, different times in my cycle, etc, the "right" answer changes. This keeps me on my toes and my awareness must be present to know what's right for now.
As a teacher, it helps to keep me humble and to know that I can never feel exactly what someone else feels. Our experiences are unique, and in seeing all of these different views from "experts", I know that each person is truly their own best teacher.
In summary, listen, learn, take what works for this moment, and store the rest. It just might be what's "right" on another day.
