Actually, I have a further point to make with this posting. There have been various accusations in the past that the Dorje Shugden practitioners were sectarian and that the practitioners are Gelug supremacist. Well, with this and other information you can read on this incredible website, you will come to the understanding that Dorje Shugden is inclusive of all sects.
There is an article I read that many Nyingma practitioners around the Gaden Phelgyeling monastery in Tibet worship Dorje Shugden! This is incredible because Nyingmas are the ones always accusing Gelugs, especially the staunch Dorje Shugden practitioners to be sectarian. The facts presented here shows otherwise. Anyway, if Kyabje Pabongka Rinpoche and Kyabje Trijang Rinpoche say he is Manjushri, then he must be Manjushri. Furthermore, Manjushri does not belong to any sect simply because he is a Buddha.
Well here is a brief History of Nyingmas.... they definitely do believe and pray to Manjushri... I suppose they are perpetuating Dorje Shugden after all.. LOLA Brief History of the NyingmaThe Nyingma School has an unbroken lineage of enlightened masters of Mantrayana and Sutrayana from the present time back to the disciples of Shakyamuni Buddha. Literally it is known as the school of the ancient ones.
More than 2,500 years ago Shakyamuni Buddha, the fourth Buddha, ushered in the auspicious time (kelpa) in which we still live and which will see a thousand Buddhas manifest in this world. He revealed himself to be a Buddha by fulfilling the twelve deeds that all Buddhas perform:
"Leaving Tusita heaven (dGa.ldan) for this world in the form of an ash white elephant
Entering into the womb of his mother
Taking birth in Lumbini, and then taking seven steps in each of the four directions
Learning the arts, such as writing, mathematics, archery etc
Engaging in sports with other young men and enjoying the company of his consorts
Abandoning the princely life at the age of 29 to become a self ordained monk
Enduring many hardships for six years by the river Nairanjana
Sitting beneath the bodhi tree at Bodhgaya
Defeating hosts of demons that night
Attaining buddhahood at dawn
Turning the Wheel of Dharma at Sarnath
Passing into Nirvana."
He turned the Wheel of Dharma three times. That is he gave three distinct cycles or cannon of teaching:
First in Sarnath, Buddha taught the four noble truths (bDen.pa bzhi) to the five noble ones (lNga.sde bzang po) being suffering, the cause of suffering, the end of suffering and the path leading to the end of suffering. This is the basis of the Hinayana.
Second at Vulture’s Peak in Rajgir he taught the perfection of wisdom (Prajna Paramita, Tib. SNying-mDo or The Heart Sutra) being characteristiclessness or "emptiness". Form is emptiness and emptiness is form. He taught this to a mixed audience of men, women, sramaneras, bhiksus, bhiksunis, bodhisatvas (including
Manjushri, Avalokitsvara, Vajrapani and Maitreya).
Finally he taught the doctrine of absolute truth to supernatural beings, gods, bodhisattvas, nagas, raksas, raksasas and human beings.
The Buddha left 84,000 kinds of teachings, enough for an appropriate teaching for every kind of mind. These can be classified in three, nine, twelve, fourteen and fifteen yanas or vehicles.
