Dear PemaTingdron
On what assumption you say that the man doing Shirasana is doing it wrong?
First of all accusation is supported by facts not by assumption. You say it looks that his entire body weight is on his forehead, but are you really sure about that. ?
FYI most of his body weight is on his elbows and shoulders.
Your comment has just reveled your ignorance?
You have 36 years of experience of practicing yoga. May I ask what have you learned or missed in yoga?
The man who is practicing Shirsasana was in terriable car accident on Highway, his sedan became hatchback. So for the facts, the rear of the car was struck. According to medical science this guy would have had whiplash because of rear end damaged. This guy had pain in his neck and in his back because of accident. He not only teaches Yoga but believes in it too. So he did not go to doctor, chiropractor or physiotherapist and was teaching Yoga next morning after accident. He practiced shirshasana and scorpio Pose after 2 days of accident.
Would PemaTingdron dare to do that?
Raise yourself beyond Asanas and open the vile of window of your brain.
OM Namah Shivaya!
God bless her!
