A lot of exercise is mindless; you can have music or the radio on and not be aware. But if you're aware in anything you do - and it doesn't have to be yoga - it changes you. Being present changes you.
Yoga teaches you how to listen to your body.
For me, first, it's finding quiet in my life - and I do that through yoga and meditation. It's also been a matter of changing the way I eat, because I think what we eat can inform who we are; food is a chemical and a drug to a certain extent.
I began by doing physical yoga, initially just for the workout, as exercise. I would get peaceful and calm at the end of it, and I was curious about that.
Starting out in a beginner class and really understanding the fundamentals of yoga is really important.
