Keeping him secret now, let's TGIE know they have failed.
Politics
Announcing it slowly is to give hope and protect his life.
People hope the politics will end. Dorje Shugden is good enough, yet another reincarnation will not solve the problem.
As long as sentient beings remain, may I too remain, to benefit the beings of the world ~ Shantideva.
Every reincarnation has a part to play, a job to do, a mission to accomplish.
Dulzin built Gaden Monastery - the original Gelugpa monastery from which came the likes of Trijang Rinpoche, Zong Rinpoche, Zemey Rinpoche...
He returned as Panchen Sonam Drakpa, composed the 11 volumes of scriptures, studied by masters like Trijang Rinpoche, Ling Rinpoche, Dalai Lama, Zong Rinpoche...
He returned once again as Tulku Drakpa Gyeltsen, who arose as the great DharmaPala Dorje Shugden, whose lineage carries on in Trijang Rinpoche, Dagom Rinpoche, Geshe Kelsang Gyatso...
Just look at his great deeds. The mindstream of a beneficial one will continue to return again and again to samsara. Whatever form they choose to reincarnate it, whatever recognition the receive, their sole purpose is to continue to benefit.
To say something is good enough, is belittling our Protector. If he has emanated once again, then it must be for great benefit.
I am not agreeing that the announcement is true and valid. But if TRUE, then there is HOPE. Hope for what? For freedom of religion, for the end of discrimination. If not, then what have we lost?
Wait and see. Why criticise prematurely?
