And you make this powerful assessment based on..... ?
Cause the more i read of TNH the more i suspect that many who knock his approach to the dhamma haven't read some of the indepth and detailed things he's written, such as "The Heart of the Buddha's Teachings"
... a book that provides the most comprehensive "popular" overview of what the Buddha taught that I've seen so far from a modern Zen teacher.
Not that his approach or teachings are flawless, or superior to what great Theravadin masters teach. I wouldn't put him up on a pedestal, but in my opinion what he's been doing is still very much the teaching of the dhamma, and very helpful to people, just from a Modern Mahayana point of view...
see for example: http://en.wikipedia.org/wiki/Madhyamaka
A focus on interdependence is one of the approaches of Madhyamaka, as i understand it, which isnt for everyone, of course.
People come to Buddha's wisdom from different directions.
There is no one single way to teach or practice the dhamma, is there?
