This is such a pity that the most renowned traditional Tibetan medicine practitioner has closed his clinic due to old age. Knowing Yeshi Dhonden is a very good Tibetan medicine practitioner, the CTA should help him to train a successor. However, the CTA has not done anything and they have just lost a very precious jewel.
This is how the CTA operates, they care only about their own interest, they don't treasure their valuable culture or resources. For example, Tibetan Buddhism is very precious, they should make sure they preserve all traditions within Tibetan Buddhism. However, what they do is to split the lineage apart and create a bad reputation for Tibetan Buddhism.
The Dorje Shugden controversy and the two Karmapas issues have put many people off from learning Tibetan Buddhism. Many people don't like it when religion mixes with politics. As a result, they learn from other lineages and they lose their faith in Tibetan Buddhism. This is how the CTA destroys the precious Tibetan culture.
