I started teaching yoga in 1974 in Colorado, I was living in Winter Park, and I started teaching skiers. At that point I was teaching more of the Sivananda system and just pushing it up a little bit to make it a little more rajasic a little more active, a little more physical. People would come, and feel great, and by the time I left Colorado in 1980 I'd taught pretty much everyone in town - the ski patrol, ski instructors, the bar owners.

I really do believe that the bottom line that creates transformation in the individual is the ability to focus your attention in an ever greater and more subtle way, and that follows the whole path of the limbs.

Separation of mind and body, that's been around since the Greeks.

I think it's really important to create spiritual revolutionaries.

Practice means making an effort to keep your mind steady. Yoga is about learning to pay attention. That's what drives transformation.

I'm really fascinated by the parallels between quantum theory and the teachings of some of these ancient texts. So many of the things that quantum physicists are talking about today, like non-locality and the observer effect, are things the yogis have been saying for thousands of years.

Lots of media people ask me what do you think of yoga in the gyms, and what do you think about this article and what do you think about that, and how about it's so commercial now. I say, look, whatever gets people turned on to it.
