The Dalai Lama is just a temporal leader of Tibet.
I became the Dalai Lama not on a volunteer basis.
I never dreamt, in my dream, I'm Dalai Lama.
I felt we must separate political responsibility. The Dalai Lama should not carry that burden. So that is my selfish reason - to protect the old Dalai Lama tradition. It is safer without political involvement.
The Tibetan people will need to determine who the next reincarnation of the Dalai Lama is.
