You can take yoga classes in yoga studios. You can go to ashrams for deeper stays. You can take yoga vacations! You can go to your gym or community centers. Workplaces offer yoga classes on site. I teach yoga in an apartment building for the residents for heaven's sake. Yoga is online, in books, on your phone, on tv, and we even have yoga apps! (See the list on the right in my blog. We've had them for years.)
How yoga is growing is a lot like yoga. Yoga expands us as people. Some of us get stretchier and maybe a bit taller through asana practice. But as you know if you read my blog, that is hardly all of yoga. A holistic yoga practice will allow you to expand in your life, taking in more and more of what life's experiences have to offer without being thrown by them. Yoga expanding has us explore our comfort zones and keep moving the edges a bit further out every time.
It looks like yoga is doing that all by itself, using us as its prana or something. It's like people are the prana for the yoga. I'm just making that up, but it seems to fit the way I'm positioning yoga at the moment. Yoga can take more and more people to deeper and deeper places.
The form yoga takes might keep shifting as less-common facets of yoga are presented for our practice and review, but clearly it has taken root in our culture and it isn't leaving anytime soon.
