Topics related to the physical practice. Subjects of more subtle nature, eg. about prana, bandha, and drishti also welcome as long as they relate to the practice of Ashtanga Yoga as taught by Sri K. Pattabhi Jois of Mysore, India
Dvarapalaka are the guardians at the temple gates. This is an area for the guardians of the lineage of Pattabhi Jois. A good place to discuss practices and forms of yoga other than ashtanga.
