Hello! Here is a link of my Yin Yoga teacher, Victor Chng. He talks about what Yin Yoga is about and a promotion of his workshop in Bhutan 
I hope someday I can attend this workshop and visit Bhutan. 
If the video doesn’t want to show, watch here from youtube.
Interested in taking his workshops/trainings? Visit his site www.yinyogainasia.com.
Namaste
