Short Biography
From Nyoshul Khenpo
"Longchenpa's main Dzogchen lineage of transmission was passed down through his disciple Khenchen Khyabdal Lhundrub and survives in an unbroken lineage to this day."
From elsewhere
"Longchen Rabjam condensed the teachings of the Vima Nyingthig and Khandro Nyingthig and gave them the names Vima Yangthig and Khandro Yangthig respectively. Since then, the profound teaching called the Nyingthig Yab Zhi came into existence that has also been transmitted uninterruptedly till now. These teachings were passed down through Khenchen Khyabdal Lhundrub."
