Why is there disharmony between Tibetan Buddhists?

[U]ntil now there have been no problems between the majority of Buddhists of the four schools such as Gelugpa, Nyingmapa and so on. We live naturally in harmony, respecting each other’s tradition and we would like this state of affairs to continue. Therefore I would like to request to the Dalai Lama, the Central Tibetan Administration in Dharamsala and the Tibetan people: could you please stop completely this meaningless talking and give everyone religious freedom to worship whoever they choose. (Geshe Kelsang Gyatso, alt.religion.buddhism.tibetan, 14 November 1997)

Before the ban on Dorje Shugden practice there was no problem. Tibetans of all four traditions lived side by side peacefully. It is the ban itself that is causing division and problems.

Within the Nyingma and Kagyu traditions some people following the Dalai Lama’s view may not have liked the practice of Dorje Shugden, but this is their choice. The majority had no problems until the ban was implemented last year. (Geshe Kelsang Gyatso, alt.religion.buddhism.nkt, 06 December 1997)
