Translation of a Chinese Bön book about Dzogchen I am looking for a translation in english (or french) of the following book in Chinese Mandarin:
大圆满前行法海
It is a book in the Bön tradition about Dzogchen.
I coudn't find a translation, but from what I gather from the title:

大圆满 Dzogchen
前行 forward, advance
法海 Fa-Hai

法海 Fa-Hai was a Chan monk in the Tang dynasty, but is also the name of a Sino-Tibetan Lama (1920-1991) who studied both Chan and Dzogchen. Monica Esposito wrote a book in English on this blending of disciplines:
The Zen of Tantra: Tibetan Great Perfection in Fahai Lama's Chinese Zen Monastery
Hope this helps.
