Ajahn Brahm (born Peter Betts, 1951) is a British-born Theravada monk who has lived in Australia since 1983: a Cambridge physics graduate who ordained in Thailand under Ajahn Chah, built the Buddhist community of Perth from almost nothing, and in 2009 took part in a bhikkhunī ordination that cost his monastery its place in Ajahn Chah’s lineage.

Most readers meet him first as a voice — the monk with the jokes, whose talks travel by podcast and whose stories are collected in Who Ordered This Truckload of Dung? The 2009 episode is the harder and more important story, and it is the reason this page exists. It is also, unusually, a story in which both sides wrote down their own account — so this page reports what each of them said, and leaves the judgement to the reader.

From Cambridge physics to a forest monastery

The Buddhist Society of Western Australia’s biography of him — the society’s own third-person account, whose latest internal figures date from 2016 — records that he was born Peter Betts in London on 7 August 1951, came from a working-class background, went to Latymer Upper School, and “won a scholarship to study Theoretical Physics at Cambridge University in the late 1960s.” He joined the university’s Buddhist Society there and, it says, “after a few weeks at the age of 18, he saw a monk for the first time.” He taught school for a year after graduating, then went to Thailand.

He was ordained as a bhikkhu by Somdet Buddhajahn at Wat Saket in Bangkok in 1974 — a detail corroborated from the far side of the later quarrel, since the elders’ 2009 statement names the same man as his preceptor and as the then acting head of the Thai Sangha. In January 1975 he travelled to the north-east and became a student of Ajahn Chah at Wat Pah Pong. That same year he joined the founding community of Wat Pah Nanachat, the international monastery set up for the Westerners arriving to train, and served as its vinaya master from 1975 until 1983. On the society’s account, his notes on the monastic code “are still authoritative for most Western Buddhist monks in the Theravada tradition” — a claim worth flagging as its own, since no outside source is offered for it.

What matters for everything that follows is that he spent eight years as the man in the room who knew the rules. The 2009 dispute was, at bottom, an argument about the Vinaya between people who had all spent their lives inside it.

Building Buddhism in Perth

In 1983 the Buddhist Society of Western Australia invited him and Ajahn Jagaro to Perth. The society bought rural land at Serpentine later that year, and Ajahn Brahm became co-founding monk and deputy abbot of Bodhinyana Monastery. He built much of it with his own hands: the society’s biography says he “built most of the structures with his own hands alongside his fellow monastics.” He became abbot in 1995, when Ajahn Jagaro left, and spiritual director of the society in the same year.

The building did not stop there. Dhammasara Nuns’ Monastery at Gidgegannup was established in 1997 with a single Australian nun; Jhana Grove retreat centre followed from 2006. He was awarded the John Curtin Medal in 2004, and in June 2006 King Bhumibol Adulyadej conferred on him the Thai ecclesiastical title Phra Visuddhisamvarathera — an honour he would later quote his own certificate for, in the letter that followed his expulsion.

What he teaches

His practice teaching is unusually specific, and it is his own rather than his tradition’s. The Basic Method of Meditation, the booklet he gives away, sets out seven stages — from sustained attention on the present moment, through silent awareness and the breath, to the “beautiful breath,” the mental sign (nimitta), and the first jhāna. Part 1 opens on the method:

The goal, he writes there, “is the beautiful silence, stillness and clarity of mind” — and he is candid that this takes time, offering the line that has become a signature: “In meditation, patience is the fastest way!” It is a samatha-first approach in which the jhānas are not an optional refinement but the point of sitting down. That is a real position in a live argument, not a neutral summary: plenty of respected Theravada teachers treat deep absorption as helpful but not required, and our page on the jhānas lays out both readings. Ajahn Brahm anchors his own in the discourses: the booklet cites the Latukikopama Sutta of the Majjhima Nikāya by name — MN 66 — for the Buddha’s contrast between two kinds of pleasure.

Alongside the technique runs the tone everyone recognises: kindness, jokes, and short stories about ordinary failure. Who Ordered This Truckload of Dung? (Wisdom, 2005; also published as Opening the Door of Your Heart) collects them; Mindfulness, Bliss, and Beyond (Wisdom, 2006) is the meditation handbook, with a foreword by Jack Kornfield. Later titles include The Art of Disappearing, Don’t Worry, Be Grumpy (published elsewhere as Good? Bad? Who Knows?) and Kindfulness (2016). For the themes those books circle, see letting go and loving-kindness meditation — the cultivation of mettā.

2009: the ordination and the split

On 22 October 2009, at Bodhinyana, four women from Dhammasara — Vayama, Nirodha, Seri and Hasapañña — received full bhikkhunī ordination. The documentation prepared for the abbots’ meeting that December records the form: a dual ordination, performed first by eight members of the Theravada bhikkhunī sangha and then confirmed by ten bhikkhus, with Ayya Tathālokā as preceptor (pavattinī). It was the first bhikkhunī ordination in Australia, and it was held inside the Thai Forest tradition of Ajahn Chah, whose mother monastery in Thailand had resolved four months earlier to follow the Thai Sangha council’s position that the bhikkhunī lineage cannot legitimately be revived.

Ajahn Brahm’s part in it is worth stating precisely, because he has described it loosely himself. Speaking to ABC News in 2019, he put it simply: “There were four very fine Australian women who wanted to become Bhikkhunis and so I did the ordination for them.” His own letter of November 2009 is more exact: the preceptor was Ayya Tathālokā, and he was one of the two bhikkhus who chanted the confirming motion in the monks’ sangha. He was a participant and the host, not the preceptor.

What he said

Summoned to Wat Pah Pong on 1 November 2009, he wrote a week later that once the senior monks understood he was not the preceptor they were ready to let it rest, provided he promised not to take part in another such ordination — which, “remembering the example of Venerable Ananda at the First Council,” he did, three times. Then the question turned to the four women:

He refused, and Bodhinyana was removed. “The decision to excommunicate Bodhinyana Buddhist Monastery,” he wrote, “rested solely on my refusal to state that the Bhikkhuni Ordination was invalid.” He also recorded that he had put the question of jurisdiction to the acting Sangharaja, Somdej Phra Pootajarn, “well beforehand” — and quotes the answer he received as “Thai Sangha law does not extend outside of Thailand.”

What the elders said

The Western elders of the Ajahn Chah Sangha — twenty-eight of them, including Ajahn Sumedho — met at Wat Pah Nanachat from 7 to 9 December 2009 and published their own account. (The copy quoted here, like the letters above, is the one hosted by the Alliance for Bhikkhunis.) It does not accept his framing:

Their grievance was procedural, and they were explicit that it was not, in itself, opposition to ordaining women: “The source of these feelings was not outright opposition to bhikkhuni ordination as such (in fact a number of our Western elders consider the arguments supporting its legitimacy to be well-founded), but the sense that the way the ordination had been arranged constituted a serious betrayal of trust.” A meeting of the Western elders had already been scheduled for December with bhikkhunī ordination on the agenda — to be hosted by Ajahn Brahm in Perth — and they could not understand why it had been “rushed through” beforehand and the preparations concealed. In June 2009, they add, the Ajahn Chah Sangha at Wat Pah Pong had reaffirmed that it would follow the Thai Sangha council’s position that the bhikkhunī lineage cannot be legitimately revived, and membership was understood to depend on upholding it. And they dispute the picture of the 1 November decision as a formality nodded through: the resolution was “by no means a matter of ‘a few grunts,’ as it has been widely represented, but rather it was a rousing agreement on the part of the 160 strong monastic assembly, with Ajahn Brahmavamso himself providing the solitary voice of dissent.”

The same statement also defends the siladhara order at Amaravati and Cittaviveka, and the “five points” Ajahn Sumedho had set out for it — a separate dispute that ran alongside this one, and that the elders say was misrepresented.

The argument underneath

Both sides also fought it as a technical question of monastic law, which is what makes it a Vinaya case rather than only a political one. At the request of Wat Nong Pah Pong’s administrative council, the American scholar-monk Thanissaro Bhikkhu reviewed the ordination proceedings and wrote a letter dated 13 November 2009. We have not read that letter, so it is described here only as his respondents describe it: Ajahn Brahmali’s reply says it makes the case “that ordaining 2 or 3 bhikkhunīs simultaneously is invalid and, consequently, so was the recent ordination in Perth.” The compilation’s own preface adds that it was offered as a tentative argument for the abbots’ consideration by a consultant with no authority over Vinaya in that community — a characterisation supplied, it should be said, by the side that disagreed with it. The replies assembled for the December meeting were signed by Bhikkhu Bodhi, Ajahn Brahmali, Ajahn Sujato, Ayya Tathālokā, Ayya Sudhamma and Bhikkhu Anālayo. Ajahn Brahm’s own contribution, dated 23 November, allows that arguments from inference on the Vinaya “will always be ambiguous,” and asks for a rule of thumb instead:

This site does not adjudicate it. What can be said plainly is that the Vinaya question and the procedural question are different questions, and that the elders’ statement answers mostly the second while Ajahn Brahm’s letters answer mostly the first. For the wider history of the lineage they were arguing about — its lapse, and its revival from the 1990s — see bhikkhunī ordination and women in Buddhism.

After the split

He did not go quiet. In January 2014 he wrote a paper, “Gender Equality and the Empowerment of Women in Theravada Buddhism,” for the United Nations Day of Vesak conference in Vietnam. It opens with Rosa Parks, argues from the Mahāparinibbāna Sutta that the Buddha’s mission expressly included bhikkhunīs, holds that the Thai council’s 1928 ban has no reach outside Thailand, and works through the four grounds on which the Vinaya says an ordination may be judged illegitimate. Its pivot is a challenge to his own side of the religious fence:

The paper was accepted and then stopped: he arrived in Vietnam to be told it would not be delivered. Sri Lanka’s Daily FT, on 12 June 2014, reported his account from his weekly Dhamma talk — “I was told it has been banned. I knew it was unfair for anyone to do such a thing.” — and his own dry reading of the outcome, which was to thank the committee: “Their action gave it more power. Now you can see it on the Internet.” He was right; the text circulated online instead, which is where it can be read today.

In the 2019 Queen’s Birthday Honours he was appointed a Member of the Order of Australia for services to Buddhism and gender equality. ABC News, reporting it, got his own explanation of 2009: “There’d been lots of discussion, lots of talk. No action,” he said. “And so it came a time, when I decided something has to be done.” The expulsion, he told the broadcaster, was a sacrifice he was willing to make. The nomination had come from Cecilia Mitra of the Federation of Australian Buddhist Councils, and had taken eighteen months.

That is the quietest measure of what happened. Losing the branch listing did not disrobe him or dissolve his monastery; it severed an affiliation. Bodhinyana and Dhammasara continued, and as of September 2026 the society’s teacher page still describes Ajahn Brahm as “abbot of the largest Buddhist monastery in the Southern Hemisphere.” The same teacher listing now includes Ajahn Vayama and Ajahn Hasapañña — and it was Ven. Hasapañña, whom the society identifies as one of the first four bhikkhunīs ordained in Australia, who wrote in support of his nomination.

How to place him

Ajahn Brahm is best understood as a forest monastic who kept the training and broke the network. He is not a reformer of doctrine: his meditation teaching is drawn from the suttas and aimed squarely at jhāna, and his monastery runs on the same rule he spent eight years teaching at Wat Pah Nanachat. What he did in 2009 was insist that the rule, read honestly, already permitted something his elders would not permit — and accept the cost of saying so.

Whether he was right about the Vinaya, and whether he was right to act without his elders, are two different questions, and neither is settled by his popularity or by his honours. Both sides published; both are linked above; a reader can weigh them. For the lineage he came from, see Ajahn Chah and the Thai Forest tradition; for the argument he joined, bhikkhunī ordination and the life of a Buddhist nun; and for the wider story of the tradition in the West, Buddhism in the West and the most influential Buddhist teachers.
