I have been searching this documentary of Tibetan prostrating all the way from kham to lhasa for long time. I saw this documentary couple a years ago and then it vanished out of my search site. Because its in Korean. One of the guy in here name bhutsa is related to me he passed away a coulple of years ago after this documentary was made. back in the days he used to hunt. I met him in 1991 my first visit to tibet. I even rode his white horse and fired his gun. I still remember his rifle which is similar to what indian police carry. Tibetans called it inji khadum, when he made it all the way to lhasa doing three prostration in front of the jhokang temple it was a emotional site for me. I even shed few tears. Its was personal him. for he has sinned and confessed in the melarepa way or Tibetan way.
