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. ↗
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. ↗
