establishing in Tibet

The Lamrim Yeshe Nyingpo root text says:

Invited by Manjushri's incarnation, the Dharma-upholding King Trisong Deutsen,...

The chief cause for this great master and emanation body of buddhas to personally visit the land of Tibet was the Tibetan king prophesied by the Victorious One in the Root Tantra of Manjushri.

In the successive occurrence of kings, it is universally known that Tori Nyenshel, an emanation of bodhisattva Samantabhadra, instigated the sacred Dharma. Songsten Gampo, Avalokiteshvara in person, established its tradition. Finally, the great Dharma ruler, King Trisong Deutsen, the emanation body of noble Manjushri, made it spread and flourish. In order that this sacred Dharma flourish, this latter Dharma king invited from the Noble Land of India one hundred and eight great panditas such as the great scholar Shantarakshita, Vimalamitra, who possessed the vajra body, and in particuar Padmakara, the great vidyadhara of immortality. He let the subjects with devotion be ordained and learn translation. He erected temples, established the Sangha, and founded the tradition for translating, expounding, and practicing this sacred Dharma. Thus his deeds in initially spreading Buddha's teachings will never disappear, not even at the end of existence, and the signature and fame of this demonstrate the exaltedness of the patron of these teachings. ...from The Light of Wisdom, Vol. 1, pg. 48.
