I'm interested in the biomechanics (I think that's the right term here) of meditation postures, specifically the various cross-legged postures. I currently don't have any serious knee or hip issues but I've heard stories of people damaging their knees in meditation. I don't wish to experience this. I sit cross-legged and stretch every day: eventually I would like to be able to sit half or full lotus and I want to do this safely and armed with knowledge. Does anyone know, have recommendations, or can point to where are the following:
*Studies on the meditation postures, specifically the cross-legged posture: peferably peer-reviewed, in meditation or otherwise: long-term effects of the various cross-legged postures on knee health, ankle health, hip health, pain, mobility, etc.
*Web sites or books on the subject: all I've seen so far are very general recommendations, nothing explaining the actual mechanics of sitting.
*Teachers on the subject: I'm guessing a few yoga teachers are versed on the complex anatomy and physiology of this subject but I'm sure not all are. What other professials would be experts in this subject?
By the way, I live in the San Francisco Bay Area so if anyone has a reference to a truly outstanding knower of the human body in California, especially in relation to this subject, I would love to know! That is my real goal in this regard: to find a master of the human body who can expertly diagnose you then tell you exactly what you need to do to relieve pain, achieve a certain posture, etc. based on your own personal situation. I think I met a person like this a long time ago but sadly I do not have their contact information.
