"Tibet possesses a literature that stretches back over 1300 years. It is one of the great literary traditions of Asia, in terms of both its size and range of influence. From ancient pillar inscriptions, to manuscripts sealed away in long-forgotten caves, to block-printed texts on every imaginable subject piled high in monastic libraries, the Tibetan corpus numbers tens of thousands of works. It has exercised an abiding influence not only in Tibet itself, but in the larger cultural area at one time dominated by Tibet, which includes Mongolia, Ladakh, Nepal, Sikkim, Bhutan and parts of northern Pakistan, northern India, western China and southern Russia."
