I'm curious why so many people seem to have an affinity for the Thai Forest Tradition? I have a great affinity for this tradition as well, especially the Dhammayut sect.
There are a few reasons which I will state.
My primary reason is Thanissaro bhikkhu. I also like the works of Ajaan Fuang, Ajaan Lee, Ajaan Chah, and Ajaan Summedho (among others.)
I think I'm primarily attracted to the Thai forest tradition because, even before I became a Buddhist, I have spent many, many, many days, alone, in the outdoor wilds of North America and have always felt a great affinity to such. I've also noticed that by maintaining a non-hateful, non-agressive demeanor, I've never been attacked by any wild animals, and I've encountered a lot, including rattle snakes, bears and cougars in the wild and have never had any problems with them. In fact, the ONLY time I've ever felt threatened by such animals was when I was with others who tend to "freak out" around such encounters. Of course, YMMV and I'm not suggesting anyone go "Timothy Treadwell" (google it) or any such thing.
Through the works of Ajaan Geoff and his primary teachers, Ajaan Fuang and Ajaan Lee, I have FELT the circulation of "chi" (breath energy) in my body and, well, this works well for me. I also absolutely dislike the "noting" techniques that some of the Burmese (and other) schools use. Having said that, I am well aware that this works well for some and I very much believe in a "to each his own" philosophy. Just one man's opinion...
