Nyingma

Nyingma School (rnying ma). The teachings brought to Tibet and translated mainly during the reign of King Trisong Deutsen and in the subsequent period up to Rinchen Sangpo in the ninth century, chiefly by the great masters Padmasambhava, Vimalamitra, Shantarakshita, and Vairotsana. The two subsequent main types of transmission are Kahma and Terma. Practices are based on both the Outer and Inner Tantras with emphasis on the practice of the Inner Tantras of Mahayoga, Anu Yoga and Ati Yoga.
