In the face of danger, His Holiness the Dalai Lama and His Holiness The Panchen Lama took the most practical and wise approach to preserving the Dharma. One escaped and the other stayed behind so that they can split the risk. Should one party fall, then the other party can continue the Teachings. Personally I think this is the true sign of enlightened minds that are not afraid of losing something as inherently impermanent as one's life.
The Dalai Lama "escaped" while the Panchen Lama was "killed". I doubt if you can kill the emanation of Amitabha unless the Panchen Lama felt that since the Dalai Lama was safely away, the best thing to do would be to "die" so that the Panchen Lam's next reincarnation can take birth quickly and be of the right age when the Dalai Lama is ready to pass the baton as it were.
The 11th Panchen Lama which I firmly believe to be the same mind stream as the 10th Panchen Lama is now ready to take world prominence and with the backing of the Government of the most populous country in the world. Imagine if the 10th Dalai Lama is still alive and is still another symbol, other than HHDL, of defiance to the Chinese. There would be no Chinese backing.
And with this new development, His Holines the Dalai Lama is preparing to retreat so that the 11th Panchen Lama can more easily be the next world symbol and leader of Buddhism. The suggestion by the Dalai Lama that there may not be another Dalai Lama is very much in line with the strategy to stay focussed and promote the 11th Panchen Lama.
At some point, HHDL will go into clear light and the world will turn its attention on the 11th Panchen Lama. With the passing of HHDL, the Shugden ban will disintegrate. The 11th Panchen Lama will then pave the way for Dorje Shugden to be the widest Buddha practice in the world.
Avalokiteshvara and Amitabha have long understood the duality of the human mind and have played a very effective strategy to spread the Dharma through the practice of Dorje Shugden, recognized to be the most effective for our time.
Just look at the nett results of events in the last half century or so when Buddhism was in decline.
