CTA should look after Dalai Lama very well. Once Dalai Lama enters clear light they are on their own and all the funding it is actually from Dalai Lama and not from Sangay. What Sangay should also do is to work hard and bring Dalai Lama back to Tibet. It’s important for Dalai Lama go back to Tibet to stabilize the Tibetan there and planning for Dalai Lama future rebirth.
It is too late to plan for all of these. The Tibetan government had their chance, and they did not treasure it well. With the current situation, there is no way His Holiness the Dalai Lama can go back to an independent Tibet anymore. The karma for that had passed, and even His Holiness urged to aim for Umaylam (autonomy) and not Rangzen (independence) anymore.
His Holiness is over 80 years old now, and it is a common age where high lamas enter into clear light. If he is not around anymore, the fate of Tibetans in exile is doomed. The current Tibetan leadership will not be able to lead the Tibetans back to Tibet.
Rather than looking for ways to support His Holiness in bringing Tibetans back to Tibet, the Tibetan government are wasting time here and not doing what they are supposed to do and failed for 60 years. Once His Holiness is gone, Tibetans in exile will probably leave Tibetan settlements in India to join India or other countries..
