Lama Vajranatha is a truely great scholar / practitioner / Teacher.
He fearlessly turns the Wheel. http://vajranatha.com/schedule.html
His new book is extra ordinary http://www.amazon.com/Practice-Dzogchen ... 9937506670
Remembering that words about Dzogchen are not Dzogchen, these are pretty good words describing Bon Dzogchen practices.
It appears that nothing was left out. Find a Bon Master and go for it.
