Vairotsana of ''Pagor'' was a Tibetan translator living during the reign of King Trisong Detsen (who ruled from 755 until 797). Vairotsana, one of the 25 main disciples of Padmasambhava, was recognized by the latter as a reincarnation of an Indian pandita. He was among the first seven monks ordained by Shantarakshita, and was sent to India to study with Shri Singha who taught him in complete secrecy. Shri Singha in turn entrusted Vairotsana with the task of propagating the Mind section and the Space section of Dzogchen in Tibet. He is one of the three main masters to bring the Dzogchen teachings to Tibet, the two others being Padmasambhava and Vimalamitra. He was also a significant lineage holder of Trul Khor.
