Major tectonic shifts in the modern yoga world have created an entirely new landscape for both the industry and consumers. The founding generation of yoga trend-setters, whose innovation and entrepreneurial spirit fostered what is now established convention, have largely achieved the goal of ushering yoga into the mainstream of society, and no longer speak from the same obscure mantles.

Regardless of ones station, there is little chance of making it through a lifetime without some amount of difficulty and pain. Acknowledging this fact is useful in potentially encouraging more plausible expectations and acceptance of the way things are. However, too often, this inextricable truth is misperceived and becomes an enabler for imposing needless suffering upon ourselves and others.

Referring to a yoga center with the caveat: "it's not-for-profit" often carries with it an assumption of merit. Given the humanitarian and universal nature of yoga, taking the profit motive out of the business model seems ideal. However, a further examination of the trade-offs involved in opening both for-profit and not-for-profit yoga centers challenges this assumption.

Adepts have told us that yoga can be found in anything. But does that mean that anything can be yoga? With all the mixing and combining of yoga with other activities going on these days, the line between what constitutes a yoga practice and what does not has certainly become blurred and invites us to wonder why so many people find yoga insufficient on its own.

When we criticize the "yoga industry" or "commercial yoga", who exactly are we referring to? Yoga Journal? Yoga Alliance? Lululemon? Big name yoga teachers who have managed to make a buck? Or perhaps, it's really just the commodification of yoga that presents us with an unresolvable dilemma and no place in particular to point the frustration.

According to the American Medical Association, 80 to 85 percent of all human illness and disease can be attributed in part to stress. Over two-thirds of all office visits to physicians are for stress-related illness. In a recent study, 75 percent of yoga students reported attending yoga classes for stress management.

Fierce debate springs eternal among yoga enthusiasts regarding the merits of purely fitness-based sensibilities in yoga practice. Usually, it starts with someone from the more-than-fitness side feeling compelled to say out loud that Yoga is not just working out. To which, the inevitable response is who are you to define yoga or pass judgement on anyone else?

Whenever I watch the latest viral video of a scantily clad babe doing acrobatic yoga in her living room, something in me laments. I realize that these videos serve as inspiration to others and I appreciate the beauty, skill and sense of personal empowerment they represent. But I can't escape the feeling that these displays are better left to the performing arts than to a yoga mat.

With all the deserved criticism being leveled upon the yoga industry of late, it's important to distinguish between the influence of corporate business and what is happening at the grassroots. There is no better example of the disparity between these two mores than the efforts of Yoga for NY, an organization that formed to see the interests of yoga are represented in local government.

Apparently, yoga originates from Tantric sex cults. So says the senior science writer at the NY Times in a sequel to his debut about how yoga kills. Scholars have long debated the origins of yoga, which existed as a purely oral tradition for thousands of years. But evidence of an ancient document stating that cobra pose is for sexual arousal doesn't mean that yoga originated from Tantric sex cults.

The other day I was at Staples printing up some new student cards. A woman standing next to me noticed that I was doing something for a yoga center. She told me that she loved yoga and was curious what kind of yoga they practice. After learning I was the director and we have a therapeutic orientation, she asked me if I could recommend some poses to help a situation with her lower back.
