does someone have information or knowledge about this cycle other than the history and the lineage where it comes from, that i have found out already.
im interested that is this cycle part of longchen nyingtik?
im also wondering that what is the ngondro in vima nyingtik before being able to practice trekchö and tögal?
and also are there any nyingma monasteries in india that have lamas who uphold this lineage?
what about nepal?
many thanks already.
You might have learned from the link that it's a part of Nyingthig Yabzhi. Whoever holds the Nyingthig Yabzhi lineage has its lineage, of course. And I believe most of qualified Nyingma lama has this lineage. As for if they are willing to give this teaching to you, it's another question. Traditionally, it is a teaching that is not often given.
For basic ngondro, I believe that Jamyang Khyentse Wangpo wrote a short ngondro text especially for this. For Dzogchen uncommon ngondro (or say, rushen), you need to follow guru's instruction.
