When I teach a new group of students, I introduce some yoga philosophy, but I don't overload them with information. Just enough so they understand the real tradition behind this ancient practice and that it's not a stretching class. Guys come in and they're a little nervous. I tell them that when they cross the threshold of the door, they're crossing to a different dimension. They're moving from an externally-oriented reality to an internally-oriented one.

Ninety percent of what most yoga teachers do is teach asana practice. While asana discharges stress and so forth, it was never intended to be a standalone practice. The true intent of yoga is personal transformation. What we get out of the privilege of teaching prisoners is the opportunity to focus on our own personal development. You can be of service, and, while helping others transform their lives, you have the deeper opportunity to transform your own. What we teach in prison is how we live our lives.

There's often an assumption you're more privileged if you belong to a family with people who have made a success.

When you're on the yard, prisoner politics dictate that you only socialize with your own race. If you fraternize with other races, you can get taught a painful lesson. And there are inmates with a level of consciousness who feel it's their duty to enforce this segregation.

The code that most prisoners live by is an extension of the masculine roles they were taught growing up, how they were conditioned about what it means to be a man: you've got to be strong, you've got to be tough, you've got to be in charge.
