The ending part is called "天葬“. Among so many styles of funerals, this uniquely belongs to Tibet. Several years ago when I was about 14 years old, I accidently watched a video recording the process of 天葬, I guess that's not shot by the official because the video showed all the bloody parts like cutting on the body(to let the vultures smell the flesh and blood), and, the vultures eating the body. I just saw a man drived a dead woman wrapped by some fabric on a motorbike and then he revealed the fabric tying the woman's head to a wooden stake. Then he used a knife to cut on her body everywhere, seperating the flesh. That is my nightmare but I felt better when I got to know that this is the most sacred way to disappear in the world, even not everybody could get such a treat when he wants. Let the body return to the sky, that's the final dream of them.
