Thanks for posting this. Yoga if done correctly should not make you tired. It should leave you in euphoric and blissful state devoid of almost all negative emotions. This then puts in the right state to do meditation. It took me years to get this right. And you can't commercialize something that takes that long and is slow and gradual.
Plain and simple: If X makes you tired or judgmental or angry ..., X is not yoga.
I am not making this up. Google Scholar this.
Also, yoga teachers are not supposed to do it for money. Read up on how Gurukuls worked.
Yoga removed from its spiritual context is just a kitschy low grade thing that may hurt you while taking your money.
