I don’t like complaining about something without giving some solution.  The solution to the current trend of commercializing Yoga is, in my mind, quite simple.  TEACH.  Teach others what Yoga truly is!  Teach the Yamas and Niyamas in every Yoga class.  Teach the truth of Yoga instead of trivializing it as the latest exercise program.  LEARN.  Learn what Yoga really is.  Learn its great history instead of swallowing the pap of those who claim that it’s not Yoga if it doesn’t look good.
