It is only logical for us to conclude that now that the CTA have lost faith in Nechung, articles of Nechung, re- his origin and reasons why he is held as an Enlightened Protector, have been removed from the CTA websites.
The CTA have lost their faith in Nechung because of the many mistakes Nechung has made in his prophecies, including those concerning Tibet's independence. BU asked questions like "If Nechung were enlightened, why has he made so many mistakes in his prophecies?" and " If Nechung were enlightened, why does Dorje Shugden need to take over as Chief of Dharma Protectors in the prophecy of Changing of the Guards?"
I would like to address all this by way of looking at it as part of 'a bigger picture '. Tracing back to how Duldzin Dragpa Gyeltsen made the promise to arise as a Protector to protect the lineage teachings of Je Tsongkhapa , and later how Tulku Drakpa Gyeltsen arose as Protector Dorje Shugden, i see a play of enlightened activities in the minds of enlightened beings that we ordinary beings cannot fathom. Nechung appeared a s a bird that hovered over Je Tsongkhapa while he was teaching, causing Duldzin(Tsongkhapa's direct disciple) to notice it. Then Nechung transformed from the bird and revealed himself to Duldzin and asked if he could promise to arise as a Protector to protect Je Tsongkhapa's teachings, especially in these degenerate times. Duldzin agreed.
When it was time for the promise to be fulfilled and carried out, Nechung appeared to Tulku Drakpa Gyeltsen and asked him to honor and fulfill the promise that Duldzin had made to him. Nechung said he would create the conditions for Tulku Drakpa Gyeltsen to arise as a Protector, and he did. He created the negative circumstances of the chief attendants of the 5th Dalai Lama becoming jealous of Tulku Drakpa Gyeltsen to the point of wanting to kill him to remove him as a possible threat to the 5th Dalai Lama's position as spiritual and political Head of the Tibetans . Thus ,we can say that Nechung was a key figure in the whole process of Tulku Drakpa Gyeltsen arising as a Protector.Indeed, it was with Nechung's intervention that Tulku Drakpa Gyeltsen arose (successfully) as the Protector of Je Tsongkhapa's teachings.
To me, there is no doubt about Nechung as an Enlightened Protector when we see him playing a vital and most effective role in ensuring that Tulku Dragpa Gyeltsen remembered and kept the promise of Dudzin, and also in helping to ensure his arising as a Protector. That was in the time of the 5th Dalai Lama.
Fast forward to the present, the 14th Dalai Lama, like his predecessor, has relied heavily on Nechung to advise on personal matters and matters of state.But now, it is time for Nechung to fade away and for Dorje Shugden to arise. So Nechung keeps making mistakes. So the prophecy of the Changing of the Guards will be fulfilled.
Enlightened beings, like the Dalai Lama and Duldzin and Tulku Dragpa Gyeltsen, do not need oracles of Dharma Protectors to advise them; but the Tibetan people need to see them consult Dharma Protectors. So now the stage is set for Tulku Drakpa Gyeltsen to arise, as even the people can see that the 'power' of Nechung is fading.
