I haven’t been able to verify a lot of details, but the impression I got from the monks at Wat Nanachat who had been there at the time was quite different from the public perception. Kornfield writes:
Working on rural health and medical teams in the provinces along the Mekong River, I heard about a meditation master, Ajahn Chah, who welcomed Western students. I was full of ideas and hopes that Buddhist teachings would help me, maybe even lead me to become enlightened. After months of visits to Ajahn Chah’s monastery, I took monk’s vows. Over the next three years I was introduced to the practices of mindfulness, generosity, loving-kindness, and integrity, which are at the heart of Buddhist training.
He doesn’t actually say where he ordained, or how long he spent with Ajahn Chah. I believe, however, that he ordained in Bangkok, probably at Wat Mahathat (?), which was teaching Mahasi technique. The monks at Nanachat said that he stayed for a few weeks, and was in and out.
Most of the anecdotes he tells about Ajahn Chah are from books; or so it would seem from the basic search I did. However, in the introduction to the chapter on Ajahn Chah in Living Buddhist Masters (his first book, in 1977), he says:
As a new monk at his monastery I became frustrated by the difficulties of practice and the seeming arbitrary rules of conduct I had to follow. I began to criticize other monks for sloppy practice, and to doubt the wisdom of Ajahn Chah’s teaching. At one point I went to him and complained, noting that even he was inconsistent and seemed to be contradicting himself often in an unenlightened way. He laughed and pointed out how much I was suffering by trying to judge the others around me. Then he explained that in fact his teaching was just a balance.
I can only imagine what Ajahn Chah thought of this young American guy showing up and accusing him of being inconsistent!
You have to understand, there were hundreds of monks there, and Ajahn Chah had little time for personal instructions. Kornfield spent some time near Ajahn Chah, mostly staying at the nearby Wat Nanachat, and probably meeting Ajahn Chah on occasion together with other monks. To say he “trained under Ajahn Chah” is probably not technically incorrect, but I don’t think it really gives the right impression.
When I was around, years later, Ajahn Chah was dead and Luang Po Liem was the big boss. I met him on a number of occasions, and had some Dhamma discussion. But I’d never say I “trained under” him.
As for Jack’s teachings, many years ago I read something where he said that even if you’re enlightened you still need therapy. I lost interest after that.
That is hilariously accurate.
