First Published in 1995. The Russian original of the present work was posthumously published in 1962 in the revived Bibliotheea Buddhiea series and edited by G. N. Roerich. Improvements have been made to this title: the end-of-book notes are now arranged page-wise, and all Tibetan words are given in Roman transliteration. This book will be of interest to those already engaged in study of Western Tibet and particularly students of the history of Ladakh.
