Nice, lengthy NY Times Magazine article about John Friend, founder of Anusara Yoga, written by Mimi Swartz, long-time Texas Monthly writer. It provides a good overview of contemporary American yoga – practiced by 16 million people, often creating community in the way that churches once did, and having a $5.7 billion per year economy.
