Hi Dave, This is classic straw man stuff. Sure you can interpret the Commentaries as some academic edifice. But I don't. I read it as I think it was intended, as a report of the experience of practitioners.
I have no evidence to suggest that some particular modern practitioner, teacher, or commentator (whether a famous forest monk or not) is necessarily more skilled at Dhamma practise than the many people who contributed their experiences to the Commentaries. Or the modern teachers who have made use of that experience, and the experience of guiding thousands of students, to develop their instruction techniques.
By all means ignore the aspects of Theravada that you don't find helpful. I certainly ignore a lot of stuff I see here...
How about returning to the actual topic of: Shamatha In The Theravada Tradition
