This summa of Choegyal Namkhai Norbu’s researches is dedicated first and foremost to his fellow countrymen and women and to Tibetan youth in particular. The text was originally conceived as a set of university lectures that Choegyal Namkhai Norbu was invited to give at the University of Nationalities in Beijing in 1988, forming a first abridged version of The Light of Kailash subsequently enlarged by the author after further research; the manuscript through meticulous selection and a critical use and analysis of a vast array of literary and frequently unpublished sources became a work of 1,900 pages divided in three volumes.

The first volume, The Early Period, the History of Ancient Zhang Zhung, considers the rise of early human generations and the Bon lineages of ancient Zhang Zhung, its dynasties, language, and culture.

The second volume, The History of the Intermediate Period: Tibet and Zhang Zhung, is focused upon human generations, the Bonpo lineages, the spread of Bon during the lifetimes of the first Tibetan monarchs, the dynasties, written language, and civilization of ancient Tibet, as well as upon the reigns of specific kings, the Bon religion, and Bonpo religious figures (Dran-pa Nam-mkha’ in particular) of Zhang Zhung during that period.

The third volume, The History of the Later Period: Tibet, is concerned with an assessment of the genealogies, Bonpo lineages, royal dynasties (from the first monarch gNya’-khri bTsan-po until the forty-fifth monarch Khri-dar-ma ‘U-dum-btsan), language, and civilization of Tibet.

This amazing trilogy, aptly named The Light of Kailash, offers an open, daring, holistic, unbiased approach to the study of the cultural and spiritual heritage of Tibet and to the understanding of the origin of this fascinating and endangered civilization.
