I am doubtful of Nechung's accuracy as Nechung is still an unenlightened being.
I remember reading how the Dalai Lama did say that he foresees himself to be with us here for another 20 years. He's currently 76, so that's till 96 years old.
We would be very, very fortunate if the Dalai Lama lives till 113 though!
Everything is impermanent.
Perhaps the Dalai Lama will "lift" the ban on the practice of Dorje Shugden....
..... and perhaps scold those who gave up their practice for being so floppy and unstable. That would be a good laugh.
Or perhaps the Dalai Lama will push down Shugdenpa's even more and push the controversy into the global spotlight.
So many "perhaps". For now, I wish the Dalai Lama a very long life.
