I was addressing the intent of the story you raised. The purpose of Śrī Siṃha's teaching Dzogchen in such a ridiculous fashion had nothing to do with generally keeping Dzogchen teachings secret, it had to do with fooling the Indian King and Panditas so Vairocana could return with Dzogchen teachings Tibet.Adamantine wrote:And we are off topic again sort of-- the point isn't keeping things secret it's about authentic transmission. Shri Singha didn't just write it down and publish it widely in Tibet-- he gave an oral transmission to Vairotsana until both of them were satisfied with his understanding, then he left to return to Tibet to bring the teachings there, and transmit them from master to disciple. You can read the different lineages of Dzogchen and how they were transmitted to whom and how they were carried forth in the History of the Nyingma book of HH Dudjom Rinpoche. Nowhere does it say "and then this disciple never met a human master but found a text in a bookstore and achieved full realization after reading it over and over again". It is through the master disciple relationship that the teaching has always been transmitted- not through books - and this is what ChNN teaches and what you yourself affirmed at the beginning of the thread.
Everything in Buddhadharma needs to transmitted from master to disciple, no exceptions, even sūtra knowledge.
