Why People Differ
Lecture Notes
A student's question
The brahmin student Subha asks the Buddha directly what accounts for the differences visible among human beings — why some are short-lived and some long-lived, some sickly and some healthy, some ugly and some lovely, some insignificant and some illustrious, some poor and some rich, some low-born and some of eminent family, some witless and some wise. "Sentient beings are the owners of their deeds and heir to their deeds," the Buddha answers — and then unpacks that single principle into seven precise, paired examples.
Seven pairs, one clean structure
Each example matches a deed to a corresponding trait, stated twice — once for the harmful version and once for its wholesome opposite. Killing versus renouncing violence maps to short-lived versus long-lived. Habitually hurting others versus never doing so maps to sickly versus healthy. Losing one's temper at light criticism versus remaining even-tempered under heavy criticism maps to ugly versus lovely. Envy versus freedom from envy maps to insignificance versus renown. Withholding generosity versus giving freely maps to poverty versus wealth. Arrogance versus respectfulness maps to low birth versus eminent family. Never seeking guidance versus actively seeking it maps to foolishness versus wisdom.
Not a rigid formula
It would be easy to read this as claiming that every illness, every misfortune, traces to one identifiable past deed — but that stronger claim belongs to a different tradition entirely. Elsewhere the Buddha explicitly rejects the Jain position that all suffering is exclusively the fruit of past kamma; ordinary causes — weather, accident, other people's choices — still operate freely within a life. What this discourse establishes is a general, reliable tendency linking certain patterns of conduct to certain patterns of result, not an exhaustive forensic account of any single person's every hardship.
A conversion on the spot
Subha's response closes the discourse with a formula the canon reuses for a listener whose confusion has genuinely lifted: as if righting the overturned, or revealing the hidden, or lighting a lamp in the dark — the teaching has been made clear in many ways. He goes for refuge on the spot, as a lay follower for life.
- Seven specific deeds map to seven specific traits, each stated for both its harmful and wholesome version. A clean, memorable structure — not seven unrelated claims, but one principle applied seven times.
- This is explicitly not a claim that every misfortune traces to an identifiable past deed. The Buddha elsewhere rejects that stronger claim outright — ordinary causes still operate freely within any life.
- A general, reliable tendency is not the same thing as a rigid, universal formula. This distinction matters enormously for how responsibly this teaching gets applied to real people's real suffering.

MN 135 — The Shorter Analysis of Deeds
"Sentient beings are the owners of their deeds and heir to their deeds" — unpacked into seven precise, paired examples accounting for why people differ in lifespan, health, beauty, social standing, wealth, family status, and wisdom, without ever claiming that every misfortune traces back to a specific past deed.
Read the sutta →Discussion Questions
- The lecture notes stress that this sutta describes "a general, reliable tendency," not an exhaustive explanation for any individual's specific hardship. Why does this distinction matter — what goes wrong, ethically, if a teacher or student collapses it into the stronger, rigid claim?
- Pick one of the seven pairs (for instance, envy versus freedom from envy, mapped to insignificance versus renown). Does this pairing match your own observation of people you know, loosely and generally — or does it feel forced when applied to specific individuals?
- Subha's conversion happens "on the spot," in response to this teaching specifically. What about this particular explanation — as opposed to a different account of suffering — might make it land with unusual force for someone genuinely puzzled by why people's lives differ so much?
- How would you respond, using this sutta's own explicit caveat, to someone who used "it's their karma" to dismiss a person's poverty or illness as deserved?
AssignmentChoose one · half to one page · bring it next session
Choose one of the seven pairs and write half a page honestly examining whether your own conduct, over years, shows any of the pattern the sutta describes — without treating the result (however you assess it) as final or deserved.
Write a short explanation, meant for a student encountering this teaching for the first time, of exactly where "a general tendency exists" stops and "this specific person's suffering is deserved" wrongly begins. Use the sutta's own caveat explicitly.
Self-Check
The sutta's own page has a ten-question quiz covering the full text. Take it there before moving on.
Session 3: Why the Same Deed Doesn't Always Lead to the Same Result
A wanderer claims psychic proof that killers always go to hell and the virtuous always go to heaven. The Buddha's response is the most important caution in this entire course about how far you're entitled to generalize from a single case you've actually witnessed.
