Reincarnation is a phenomenon which should take place either through the voluntary choice of the concerned person or at least on the strength of his or her karma, merit and prayers. Therefore, the person who reincarnates has sole legitimate authority over where and how he or she takes rebirth and how that reincarnation is to be recognized. It is a reality that no one else can force the person concerned, or manipulate him or her. It is particularly inappropriate for Chinese communists, who explicitly reject even the idea of past and future lives, let alone the concept of reincarnate Tulkus, to meddle in the system of reincarnation and especially the reincarnations of the Dalai Lamas and Panchen Lamas […] Bear in mind that, apart from the reincarnation recognized through such legitimate methods, no recognition or acceptance should be given to a candidate chosen for political ends by anyone, including those in the People’s Republic of China.
