Which manuals? Thanks.
Here’s one reference, Mark:
https://newsunwesternskies.com/2013/07/02/notes-from-an-anthology-of-dzogchen-and-mahamudra-guidance-manuals/
That material referenced above is now part of the overall Dzogchen: Teachings, History, and Practices article page.
The reference above is no longer posted at this site but will be incorporated in the upcoming chapter on Dzogchen! (Chapter 8 of Section One covering “The Traditions”.)
