Hey people, let's face it. I think the institution of the Dalai Lama with absolute political and spiritual power in Tibet is too archaic for our time. When spirituality and politics are intertwined, its a recipe for disaster because people today have even less merits to understand and have faith in the Dalai Lama. Hence, with such an institution people would question and develop doubts and ultimately wrong views about the Dalai Lama. Therefore, the Dalai Lama has skillfully retired from office and ensured that the CTA are geared towards democracy by running elections and appointing the Sikyong Lobsang Sangay via these elections.
However, people look towards the Dalai Lama not for his politics but for his spiritual leadership, embodiment and teachings. The Sikyong does not fulfill this role at all and there are rumors that the Karmapa will be the next spiritual leader to take over from the Dalai Lama because of their close association in recent times. Actually a successor for the Dalai Lama is really unnecessary but considering how weakly the CTA is handling pressing issues, the Tibetan cause and not taking steps to lift the ban, a successor appears to be of paramount importance now to lead and reassure the people the way the Dalai Lama does for his people. I wonder who it will be still. Perhaps it is the Karmapa, perhaps it is Kyabje Ling Rinpoche or perhaps it would be Kyabje Trijang Rinpoche. At the moment, these 3 Lamas comes to mind and I don't have concrete reasons for these Lamas except for the Karmapa because the Dalai Lama did openly say he was grooming him.
