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.
Having obtained the supreme freedoms
and conjunctions of the precious human existence,
endowed with faith, energy, and intelligence,
Having attended on a worthy spiritual friend
and received the pith of the holy instructions,
May we practice these properly, just as we have received them,
without obstacle or interruption.
In all our lives, may we practice and enjoy the holy dharma.
