Padampa Sangye was an eleventh-century Indian yogi and spiritual master (known also as Kamalashila) who traveled widely throughout his life and brought Indian Buddhist teachings to China and Tibet.

Dilgo Khyentse Rinpoche (1910–1991) was a highly accomplished meditation master, scholar, and poet, and a principal holder of the Nyingma lineage. His extraordinary depth of realization enabled him to be, for all who met him, a foundation of loving-kindness, wisdom, and compassion. A dedicated exponent of the nonsectarian Rime movement, Khyentse Rinpoche was respected by all schools of Tibetan Buddhism and taught many eminent teachers, including His Holiness the Dalai Lama. He tirelessly worked to uphold the Dharma through the publication of texts, the building of monasteries and stupas, and by offering instruction to thousands of people throughout the world. His writings in Tibetan fill twenty-five volumes.
