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.

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.

You will surely smile with me when I say, 'Thank God one can still recognise self-pity as such and not give it any greater dignity than just that.

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.
