thank you all for the replies.
thanks for bringing my attention to sage gherandha, i got the gherhanda asmita and can't wait to start reading.
do you happen to have a method to know who is a real expert and who is not?
to practice ahimsa on one self is very good advice, thank you!
the opinion is divided about what side to do first, for me i will continue putting my right leg first. then i will do the posture again and do the left side, briefly.
