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.

Intense asana practice - too much, too soon - can have detrimental effects. It can also promote a dissociation from the personal sensitivity and self awareness that I am trying to encourage. I don't want to contribute to furthering physical or psychological trauma.

Since the late 1970's, the main focus of prisons has been punishment, not rehabilitation. It's hard to believe, but you would be hard-pressed to find a meaningful violence-prevention class in a federal or state penitentiary. And 'we the people' are footing the bill to keep these folks imprisoned. It costs on average $46,000 a year to keep an adult incarcerated in California and about the same for New York State.

If you are deeply connected with yourself, with your energy, staying awake to yourself in the moment, other prisoners tend to leave you alone.

I'm not fearful by nature, but I am vigilant. When you walk into a prison, it's important that a sixth sense kicks in.

I teach that the foundation for our practice is being able to go inward and disconnect from the busyness of our thoughts, that focusing the mind on bodily sensations and breath will ground us in the present moment. Yoga is about realizing who you really are, aside from your persona.
