HISTORY OF THE NYINGMA DOCTRINE
Historically the Land of Snow had many Dharma sings who were manifestations of the Lords of the three Families: Avalokiteshvara, Manjushri, and Vajrapani. The dharma first originated in 433A.D. during the reign of the 28th King, Lha-Tho-Tho-Ri-Nyentsen. When he was 60, a Buddhist scripture called Pang Kong Chag Gya Pa descended onto the rooftop of his palace, along with a few other religious objects. During the reign of Songtsen Gampo (617-698), the 33rd King of Tibet, the Tibetan Script was created, and hundreds of temples were built, including Rasa Thrulnang. Scores of sutra teachings were translated into numerous lessons and the rules of the divine doctrine of ten virtuous actions and the sixteen worldly principles were laid down. Tibetan history considers this period as the time when Buddha dharma was firmly established in Tibet.
