Very little is known in the West about Tibetan Buddhism in comparison with other eastern religions. This is partly because the vast literature which it has produced, and which illuminates its history, is still far from accessible. In addition there exists a deep division between monastic Lamaism and religion as it is lived by the people: the former is fragmented into many schools, while the latter shows numerous regional variations. The first comprehensive account of Tibetan Buddhism to be published in English since Waddell's "Buddhism of Tibet" appeared in 1894, this translation is certain to become the standard reference work on the subject.
