Since nearly all Dzogchen texts state that you have to have accomplished Ngöndro before and have to perform your training in the main teaching (trekcho and thogel) in retreat, I know where I have to establish my trust.
Just before that happens, as I was recalling ChNN's teaching, "if ngondrö were necessary, GD would have had 4 statements,
1. The Tsiksum Nedek is addressed to someone who had already completed them.
2. The interpretation of ChNN is his personal interpretation of that text, the traditional interpretations of all other masters differ. I don't mean to judge, saying this one is good, this one is bad. I'm just stating a literary fact.
then he continues with the fact there was no necessity to do SMS.
Who claims the contrary ? You give everyone here the feeling that knowing something or having done a traditional training is a mistake. SMS is the best training you can find. So why dismiss it constantly as you clearly imply it?
There si no "traditional Dzogchen cursus",
No, there are traditional Dzogchen cursus, with a proper order of practice, a number of days(weeks or months) for each of the steps, etc. You get that in most Nyingthiks.
But he also says that whe have to do with our circumstances because we have our limitations.
You are limiting yourself by saying that there is no need for retreats in Dzogchen. Probably beginners have no needs or capacity for retreats but go say that to Shardza, Longchenpa, Jigme Lingpa, etc., and check their teachings first.
But when someone says ngondrö and retreats are "mandatory", I must that I do not agree, because that's not what my master has taught.
That's your right. All other masters I've met say the contrary. Again, I'm not criticizing ChNN Rinpoche's approach which I appreciate a lot, I'm criticizing your lack of tolerance for other approaches, in particular when they are traditional. If you don't like traditional things, that's your right inflammatory comment removed
but don't go and say that Dzogchen is like this and like that when it's not the case.
