Stress in not your enemy

I read this post form Harvard Business Review Blogs,
http://blogs.hbr.org/schwartz/2012/04/stress-is-not-your-enemy.html

Few of us push ourselves nearly hard enough to realize our potential, nor do we rest, sleep, and renew nearly as deeply or for as long as we should. What the writer says is essentially distilled into the statement, "We live by the myth that stress is the enemy in our lives. The real enemy is our failure to balance stress with intermittent rest. Push the body too hard for too long — chronic stress — and the result will indeed be burnout and breakdown. But subject the body to insufficient stress, and it will weaken and atrophy."

In my practice, I see this unfold all the time. Yoga is the sweet spot where effort and relaxation. To simplify this point further, in any pose, once you learn to stack your body and achieve enough strength to hold the pose for a few moments, it is then a subtle shift happens and you get a feeling of "sinking" in, or relaxing into a pose. Almost like let gravity take over. That is your sweet spot. When you find that balance, the potential for growth is enormous.
