There are benefits of yoga that go beyond spiritual awakening. Immediately after a session you can experience: improved brain function, lower stress levels, altered gene expression, and increased flexibility. After a few months: lower blood pressure, increased lung capacity, improved sexual function, reduced chronic neck pain, anxiety relief, relief from chronic back pain, lower blood sugar levels (in diabetics), and improved sense of balance. Over years of practicing: stronger bones, healthier weight, and lower risk of heart disease.
Yoga is a way I stay balanced in my life. Through various poses and breathing techniques, yoga teaches you that if you keep your mind calm in the midst of a storm your body will stay calm as well. And no, I'm not the worst at it.
