The book provides a complete translation of a groundbreaking Tibetan treatise on contemplation, the Samten Migdron by Nubchen Sangye Yeshe (10th century). This is one of the principal sources for our understanding of the various currents of meditation transmitted to Tibet during the early spread of Buddhism to that country. It offers a detailed window into the ways in which one of the most learned masters of the early Tibetan Buddhist tradition made sense of
the different forms of meditation practiced in his day.
