Modern day yoga in America is an interesting phenomenon. In the traditional sense, what most of us do on the yoga mat is not yoga. Although the health benefits are greater than anything else we've ever tried, many still do not consider it yoga.
It's hard to believe that an experienced yoga practitioner and Pulitzer Prize-winning author can inspire such ire, particularly when he concludes his book with a huge endorsement. Maybe those angry yogis never finished the book.
