DILGO KHYENTSE RINPOCHE (1910-1991) was a highly accomplished meditation master, scholar, and poet, and a principal holder of the Nyingma lineage. He was respected by all schools of Tibetan Buddhism and taught many eminent teachers. 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.

JAMGON MIPHAM (1846-1912) is one of the great luminaries of Tibetan Buddhism in modern times. He has had a dominant and vitalizing influence on the Nyingma school in particular and, despite spending most of his life in retreat, is one of Tibet's most prolific authors.

THE PADMAKARA TRANSLATION GROUP, based in France, has a distinguished reputation for its translations of Tibetan texts and teachings. Its work is published in several languages and is renowned for its clear and accurate literary style.
