Dorje Lopön

Gyaltsap Rinpoche as Dorje Lopon making offerings prior to the Mahakala Torma being consumed.

In Tibetan Buddhism, Dorje Lopön (Tibetan: རྡོ་རྗེ་སླb་དཔོན་, Wylie: rdo-rje slob-dpon) is a title given to high-level monks who preside over tantric rituals. The equivalent Sanskrit term is vajracarya ("indestructible master"). Dorje is the Tibetan equivalent of the Sanskrit vajra and therefore the term appears frequently in Tibetan Buddhist terminology relating to Vajrayana tantra. The Garchen Tripa Dorje Lopon appeared in the 1967 third ranking of the religious dinitaries of the Kagyu school, based on those who had left Tibet for India.
