Please pay for class before you practice, rather than after.
No photography is allowed to be taken of folks while they're practicing, by me or anyone else. Your image is not a commodity for my Instagram. Pictures of the empty space are fine. Exceptions to this rule are few and far between and mutually agreed upon ahead of time.
I do not have a guru. I have teachers whom I respect and admire and know that they are human and fallible. There are no pictures of Pattabhi Jois displayed in the spaces where I teach.
