Very interesting, Bhante.
I am not too familiar with the work of either of the above monks. I read 'Clearing the Path' by Venerable Ñāṇavīra Thera a few years back and I remember it being one of the most inspiring pieces of Buddhist literature I had ever read and it still stands out today.
I have been studying Venerable Punnaji's model of the paticca samuppada. His model and the one introduced in the article, while they vary in regards to the concepts used to explain the process, seem to compliment each other nicely.
Thank you very much for posting this.
