I bicycle over a hundred miles per week. I rock climb every chance that I get. I am a committed vegetarian. I am pushing this old body of mine hard and feel that it is Yoga which is responsible for keeping it energized and unbroken. But Yoga is much more than stretching and physical health.
Yoga is also spiritual and thus infinite, a very deep subject indeed.
I can only begin to tell of what it has done for me, as its story is yet unfolding within. Yoga has enriched my spirituality. For example, most lower back pain and injuries are directly related to tightness in the hip flexors, abductors, rotators, quadriceps, Achilles tendon, and calf muscles due to the lack of stretching and mobilization. This neglect often leads to back sprain, herniated disc, and sciatica. It is very important to athletes, injured performers, and others to stretch properly.
