You mean this part?
Chögyal Namkhai Norbu will teach from what is considered to be the most important of all Dzogchen texts. Dra Thalgyur (sgra thal ‘gyur) is the abbreviated title of the Dzogchen Upadesha Tantra named rin po che 'byung bar byed pa sgra thal 'gyur chen po'i rgyud. Guru Garab Dorje re-transmitted this tantra about 300 years before Jesus was born.
The Dra Thalgyur has 6 chapters with a total of 168 questions & answers in about 200 folios. These questions include everything we always wanted to know about Dzogchen but did not know how to ask. It is the most important Dzogchen text but it is very difficult and condensed. During a period of about 3 years, Chögyal Namkhai Norbu edited 2 editions of Vimalamitra's commentary on the Dra Thalgyur. Korde Randrol ('khor 'das rang grol) means the self-liberation of samsara and nirvana. We are very fortunate that Chögyal Namkhai Norbu will transmit these profound teachings in this "open to everyone" webcast !!!
