Ethics: the Five Undertakings
The whole of the Inward Way's ethics is five undertakings. Each is renewed rather than enforced, each is reasoned from the same diagnosis the rest of the book works from — grasping, and the friction it makes — and each can be checked by one person, watching one hand, for one day. The structure is kept from the five precepts of the Buddhist tradition, credited below and on the sources page; the reasoning is the editors' own. There are five because five undertakings fit on a hand, and nothing more is asked of anyone.
Why undertakings, not laws
A law is held in place from outside: a rule, a judge, a consequence for breaking it. An undertaking is held by the one person making it. This is not less strict, only differently held: the renewal, said each morning, is the whole mechanism (see I.56).
A law implies a ledger: a tally of days kept and broken that can run into debt. Book I is explicit that no such tally exists here — no enforcer, no confession required before an undertaking can be picked back up (I.56). The Way is not the first to locate the whole matter inside the one acting. A verse of the Dhammapada puts it more plainly than we could:
"By oneself the evil is done, by oneself one suffers; by oneself evil is left undone, by oneself one is purified. Purity and impurity belong to oneself, no one can purify another." (Dhammapada 165, tr. F. Max Müller, Sacred Books of the East X, 1881)
A failure, on this account, is not a debt now owed to a judge. It is a grip — a wound made carelessly, a thing taken without asking, wanting given the wheel for an afternoon — and a grip, in this book's terms, is exactly the kind of thing that can be seen and loosened. The undertaking survives its own breaking by being said again the next morning: I undertake, not I have kept. Where the failure wounded someone else, the outward move — mending — is described at /practice/mending.
The five
Each is given below with its reasoning, its test, and a misreading to head off.
Care with harm
I undertake not to make the avoidable wound.
This is not a claim that harm can be avoided altogether — two people's wants sometimes collide with no soft way through, and that kind of harm is not what this addresses. It addresses the wound that did not have to happen: the sharp word thrown because it felt good in the mouth, the corner cut because no one was watching. Avoidable harm has a traceable source — carelessness, appetite, or the wish to win — and a traceable source can be watched (I.51).
The test: notice small avoidable wounds before they land, not after. A misreading to head off: this is not a demand for a harmless life. The claim is narrower and checkable: an avoidable wound seen a half second before it lands tends not to land. Watch for a day and count.
Care with taking
I undertake to take only what is given.
Taking is not only a matter of objects. Credit for work not fully one's own, an hour of someone's time spent without asking, attention pulled by force rather than offered, are all takings, and none appear on a ledger (I.52). A ledger tracks amounts; this undertaking tracks something a ledger cannot see — the moment before a hand closes.
The test needs no witness: a gift received and a thing taken feel different from the inside, even holding the same object — a specific tightness that a taking carries and a gift does not. A misreading to head off: this is not a rule about property; the undertaking is about that moment, not who legally owns what follows.
Care with appetite
I undertake not to let wanting steer me into harm — mine or another's.
Wanting itself is not the target; a want, looked at, is weather passing through a body, not a command (I.8, I.53). What it names is the failure where wanting takes the wheel and the looking stops — including where this is hardest to say plainly: wanting another person's body, life, or attention is not itself the fault.
The test: keep one strand of attention on a strong want as it rises, rather than climbing fully inside it, and notice whether the other person stays a whole life still holding their own hand, or becomes a shape the want has already decided about. A misreading to head off: this is not a call to want less, which would only be another grip — this time on the idea of a self who wants nothing.
Care with speech
I undertake to speak what is true and useful, and not to tighten another person's grip.
Truth alone is not the whole test: a fact can be handed over edge first, and flattery is often true and still feeds a wanting that did not need feeding (I.54). The Buddhist tradition states a version of the same standard directly — in the Abhaya Sutta (Majjhima Nikāya 58) the Buddha describes speaking what is true and beneficial, timed rightly, even when unwelcome — and the fourth undertaking keeps that structure.
The test is one check before speaking: is this true, and is this useful. A misreading to head off: "useful" does not mean comfortable, and the undertaking does not ask a speaker to soften every hard thing; a hard truth carried at the other person's pace passes the test exactly as it stands (I.63).
Care with clarity
I undertake to guard the instrument.
Every other undertaking depends on a hand that can see what it is doing, and attention is that instrument; the fifth undertaking protects the tool the other four use (I.55). Intoxication clouds it, and so, more quietly, do things that hold attention by feeding it rage and craving rather than calm, built for that or not (widened from drink; see /philosophy/technology).
The test is daily: noticing what leaves the instrument sharper and what leaves it duller, and choosing with that in view. A misreading to head off: this is not abstinence handed down as a rule; it is not a rule against anything in particular, only care, practiced daily.
Credits
Each undertaking descends from one of the five Buddhist precepts: harm from killing, taking from theft, appetite from sexual misconduct, speech from false speech, clarity from intoxicants, widened here from drink to whatever clouds attention (/philosophy/technology). Kept is the count and target of each; left is the command — these five are reasoned, not commanded — both directions set out at /sources. The verse above is Müller's translation (Dhammapada, Sacred Books of the East X, 1881), the edition this site uses for the Dhammapada.
Why five, and nothing else
Five undertakings, one for each finger of the hand, and nothing more is asked of anyone. The limit is deliberate: no dietary rules, no dress, no sexual code beyond the third undertaking's care, no ritual duties, no accounting of merit. The Way builds nothing on top of the five; it stops there and calls that complete. Money, work, and giving have their own page: /philosophy/money.
What the Undertakings are not
They are not a theory of ethics. There is no formula for weighing one against another when they pull apart. When that happens, the book offers only this: look, choose, and carry the result with an open hand. This is thin on purpose; a thicker answer would be a fixed rule standing in for the looking, the one thing the practice asks a person not to replace.
Nor is this a legal or political program: the Way says nothing about what a society, a government, or an institution should do; it speaks to one hand. And it is not a purity system — no state of having kept the five puts a person above someone still working at them (see I.65).
Objections
Too thin: nothing here on justice, on animals, on the unborn, on the planet. Fair, and it stands: five undertakings say nothing directly about any of these. The wider hand widens tending without a program (I.64) — but a program is exactly what the Way declines to write, because claiming to know what is owed at a society's scale is a grip on being right at scale, and a claim about the world besides, which the Way does not make.
Undertakings without enforcement are toothless. Concede the frame: nothing outside a person holds any of the five to it, and someone determined to ignore all five will find nothing here that stops them. But the tooth was never meant to be outside. It is the tightness of a taking, noticed in the hand that takes it (I.52), and a person who feels nothing when the undertakings break has no use for this page.
Care with speech just means "don't offend," which is self-censorship. The risk is real. But true and useful is a check applied to the speaker's own hand, not a rule for anyone else's mouth, nor a demand for comfort: a hard truth, carried at the other person's pace rather than thrown at the speaker's own, passes the test as written (I.63).
Try this
Pick one undertaking this morning and say it, plainly, the way it is written above. Through the day, watch for the tightness it is built to catch: an avoidable wound about to land, the tightness of a taking, wanting in the driver's seat, a sentence about to leave the mouth that is accurate and still a blade, the instrument going duller under something built to dull it. Notice, once, honestly, whether the undertaking held. If nothing in a full day gives you anything to notice, the claim has failed for you today, and that is the answer this page asked for.
