(...)The Authenticity of the Traditions of the Dohas and Dzogchen
The First Panchen Lama decisively states, "They are in no way incorrect texts."
A similar question arose with regard to dzogchen in the collection of Kaydrubjey's Answers to Questions in his Miscellanous Writings. Someone had remarked that certain people at that time were denigrating practitioners of dzogchen, and had asked whether the dzogchen teachings were pure. Kaydrubjey has answered, "The dzogchen teachings are definitely pure. The criticism of dzogchen practitioners is because there are certain individuals among them who practice a contrived version of dzogchen that they have made up from their misunderstanding. Basically, however, dzogchen presents a path that is harmonious with that of anuttarayoga tantra."
A certain Indian translator in Tibet at that time, Kaydrubjey continues, "had seen certain dzogchen texts in Magadha in the possession of some learned Indian masters there. Furthermore, many excellent practitioners in Tibet have achieved advanced pathway minds and bodhisattva levels based on dzogchen practice. Therefore repudiation of these teachings is an appropriate cause a fall to rebirth in one of the three worse forms of life."

Khédroup Djé est l'un des deux proches disciples de Djé Tsongkhapa, fondateurs (avec Gyeltsap Djé) de l'école Guélouk du Bouddhisme tibétain. Je lis un texte de Khédroup Djé en ce moment et il est loin d'avoir la langue dans sa poche. Si le Dzogchen n'était pas un enseignement bouddhiste authentique, il l'aurait verbalement massacré.
