The Gyuto Monastery is one of the most famous monasteries in Tibet and specializes in the study of Tantric meditation, Tantric ritual arts and Buddhist philosophy. The main disciple of the first Dalai Lama, Jetsun Kunga Dhondup, founded Gyuto Monastery in 1474 in eastern Tibet.
The Gyuto monks practice the major Tantric texts such as Guhyasamaja, Chakrasamvara and Yamantaka and have passed these lineages on to the younger generation of monks for over 500 years without disruption. As a result of the communist Chinese invasion in 1959 the Monastery was re-established in India. To accommodate the growth of the monastery to over 500 monks it has recently been relocated to Dharamsala near the residence of His Holiness the Dalai Lama.

Due to the untiring efforts of enlightened leaders, scholars and translators, Buddhism was established in Tibet with the translation of the Buddhist canon and transmission of uninterrupted oral traditions. Tibet became a Buddhist country possessing the complete teachings of sutra and tantra. Gradually four lineages developed based on specific lineages of teaching, different interpretations and different locations.
The last of these, the Gelug lineage, was pioneered by the great saint scholar Tsongkhapa who revitalized and reformed the practice of sutra and tantra. His tradition of tantric teaching was mainly established in the tantric monasteries Gyudme and Gyuto where it was promulgated and practiced.
