Сонгцэн Гампо
While in the eleventh and twelfth centuries there were several parallel narratives of important founding figures like Padmasambhava, Vimalamitra, Songtsän Gampo, and Vairotsana, by the end of the 12th century, the Padmasambhava narrative grew to dominate the others, becoming the most influential legend of the introduction of Buddhism to Tibet.
