I have spent tens of thousands of dollars for yoga training. (And still continuing that training, by the way). The majority of yoga teachers are certainly not making the big bucks. I wonder if it is all worth it.
Then I remember how much money I have saved in doctor, hospital, medical, and therapy bills and it brings it all into balance again. So to all those who are out there working on healthy bodies/healthy minds keep it up. You are rich beyond belief.

“Any devoted action offered up without desire for reward, but with the entire mind focused on the action for its own sake, is in the true spirit of scripture and is a our sacrifice.” The Living Gita 17-11
