I read somewhere that Setrab is enlightened though he manifests in worldly form, which is similar to Dorje Shugden. So could it be that Pehar/Nechung is enlightened but manifesting in worldly form?
I have read in "Oracles and Demons of Tibet: The Cult and Iconography of the Tibetan Protective Deities" by Rene De Nebesky-Wojkowitz about how Nechung will get enlightened and leave, and Dorje Shugden will become the next Protector of Tibet. There is even a map of the Nechung Chapel/Temple where the main gate is closed and apparently awaiting the arrival of Dorje Shugden. I find this fascinating and wonder when that will be. HH the Dalai Lama MUST know this, especially as he communicates with Nechung all the time, and he should know of the prophecy also. When Dorje Shugden becomes the protector of Tibet, it will also fulfil the prophecy of the 16th Karmapa who said that “Although the time is a little early but in the future, you will definitely need to rely on this deity.”
http://www.dorjeshugden.com/forum/index.php?topic=2651.msg35795#msg35795For the Karmapa to say that, it is obvious that Dorje Shugden is not a sectarian practice but that Dorje Shugden will be relied on by everyone in future.
