Boundless in Every Direction

四梵住 — loving-kindness, compassion, joy, and equanimity, radiated without limit
4 sessions · all live No prior course required Taught in English Free · every text on this site

Two young brahmins once argued over whose teacher had correctly taught the one true path to union with Brahmā. The Buddha's answer to them anchors this course: not a competing ritual claim, but four cultivable states anyone can develop and check for themselves — loving-kindness, compassion, joy, and equanimity, radiated without limit in every direction.

This course reads four suttas that build on each other: the foundational practice text itself, the argument that replaces empty ritual and lineage claims with something genuinely demonstrable, a closer look at why the four abodes are not interchangeable, and finally eleven concrete, checkable benefits of actually keeping the practice up.

Not a claim about where Brahmā lives. Something anyone can develop, and check, for themselves.

The promise of this course
Where the texts come from

All four suttas are read in full on this site, in Bhikkhu Sujato's complete CC0 translation of the Pali Canon, each with its own structured reading guide, full text, and ten-question self-check quiz. This course adds a single connecting thread across four different nikāyas; it does not retranslate anything.

What you'll be able to do
  1. Recite and explain the ethical foundation the Karaṇīya Mettā Sutta lays down before the famous wish itself — character first, technique second.
  2. Explain why the Buddha's answer to a caste-based religious authority claim is a demonstrable practice, not a competing dogma — and why that distinction matters for engaged Buddhism specifically.
  3. Name the four distinct culminations of loving-kindness, compassion, joy, and equanimity, rather than treating them as four names for one feeling.
  4. List eleven concrete, checkable benefits of a sustained mettā practice, and distinguish which register (bodily, social, spiritual) each belongs to.
  5. Carry one specific practice from this course — the mother-and-child image, the ethical floor, or the daily-life radiating instruction — directly into your own teaching or classroom.

What you'll need
  • Nothing to buy. Every sutta is on this site in full, in Bhikkhu Sujato's CC0 translation, with its own reading guide and quiz.
  • No prior course required. This course stands on its own, though The Three Fires is a natural companion for readers who want the parallel psychology of what these four abodes are actually working against.
  • A willingness to actually practice, not only read. Every assignment in this course asks you to try the radiating instruction, track a real benefit, or audit your own ethical floor — not only analyze the text.
  • Openness to an uncomfortable session. Session 2 directly challenges a religious authority claim on its own terms. Read it as the sutta itself argues, not as an attack on any tradition.
"Dependent Origination and the three fires explain what's wrong. This course is where I send students who ask what to actually do instead — and I still find it striking that the Buddha's answer to a religious authority claim was never 'believe me instead,' but 'radiate this, in every direction, and see what changes.' That is a teaching method as much as a practice, and it belongs in a school as much as in a meditation hall."
