You meet the mistaken idea that "the ultimate is unconditioned therefore anyone who teaches a path to realize it has fallen into a false view" more often in Neo-Advaita. But some would-be Dzogchenpas seem prone to it as well. I won't argue the point. But I will recommend Vivid Awareness
, a recent book by Thrangu Rinpoche made from talks he gave explaining a short text by Khenpo Gangshar. I haven't finished it yet, but so far, so good. It hits the main points that a beginner in Dzogchen/Mahamudra needs to know.
Lamrim, lojong, and mahamudra are the unmistaken path.
