This Blog will tell you things about the Tibet that was liberated by China.
News Checker: Dalai Lama, A Hero in the Western World
(If the Nobel committee finds out about all that, they will probably want his peace prize back:biggrin1
Those pictures are probably from the propaganda museum the Chinese government has set up in Lhasa, with diorama's of monks torturing serfs. Ninety percent of the tourist visitors to Tibet are Han, probably most of them believe it, and think it justifies their rule. I don't see any credibly connection with any of that with any cruelty by the fourteenth Dalai Lama. A cup made out of a skull was something that was kept around.
I have read quite a few historical contemporary first hand accounts of visitors to Tibet before Chinese rule, I don't recall a mention of flaying. Sir Charles Bell, the British commissioner to Tibet, Sikkim, and Bhutan for the first quarter of the 20thc, said that the Tibetans governed themselves more decently than did the Chinese themselves. Also that the Chinese were much crueler to subject and 'inferior' peoples. The Thirteenth Dalai Lama came close to abolishing the death penalty entirely.
Ritual use of human bones does not necessarily mean the person was cruelly treated or purposely killed. They were used for material for cups, jewelry for ritual dancers, and trumpets. Similar to a Momento Mori in European culture. A reminder of the impermanence of the earthly vessel. I'm a bit skeptical about the use of human skin for drums. The bones would have been from a highly respected person, probably a Lama, not an unknown. They would have been passed down over many generations, and used in ceremonies.
The Tibetans, like the Zoroastrians, practice 'sky burial', the corpse is dismembered, the bones are pounded up and mixed with barley flour, all is fed to vultures. I would not want to witness it. I would be glad if my remains or those of my loved ones were put to some practical use, such as feeding birds. Our practices of inhumation or cremation waste a lot of resources.
Even if some of it were true, it does not give the PRC the right to rule and exploit Tibet as a colony. The present issue is the present behavior of the CCP dictatorship.
If you would like to read some first hand accounts of the cruelty of the PRC in the first quarter century of their rule over Tibet, I suggest 'In Exile from the Land of Snows', John Avedon, 1984.
