In article The Discourse of Lama, the Qianlong Emperor stated the invention of Golden Urn is to eliminate selfish family with multiple reincarnated Rinpoches/Lamas.
[2] In Diki's biography Dalai Lama, My Son: A Mother's Story, after the murder of Reting Rinpoche in 1947 she mentioned that word started to spread that Lhamo Dhondup was not the real Dalai Lama, since Golden Urn was not used in the selection process.
To put this rumor to rest for the regent Taktra and the Kashag, it was decided to use a lot-drawing process by placing both names in a vessel before the image of Je Rinpoche to confirm the real 14th Dalai Lama.
Name Lhamo Dhondup leaped out three times, and the regent Taktra and the Kashag had nothing more to say for themselves.
"[3] Tibet expert, professor Shen Kaiyun (沈开运) of Tibet University clarified that Diki Tsering's husband Choekyong Tsering (Chinese:祁却才让) died in 1947, shortly after, Reting Rinpoche also died in 1947, both were allegedly poisoned.
