You reap what you sow — an inescapable fate.
因果應報 (인과응보) means The law of cause and effect — that the consequence of one's own actions, good or bad, inevitably returns to oneself.. nemesis means Inescapable retribution, or the being that carries it out — the force of ruin that inevitably comes for the arrogant.. Two cultures point to the same truth in different languages.
The Meeting
In the 5th century BCE, the Buddha taught that "one harvests the fruit of the seed one has sown" as a fundamental law of the universe. In Greece around the same time, the goddess Nemesis (Νέμεσις) was worshipped as a divine being who delivered retribution upon human arrogance and excess. The languages of the two civilizations differed, but the message was the same: every action is followed by a consequence, and there is no being who can escape that consequence.
The Eastern Story — The Law of Seed and Fruit
The phrase arises from one of Buddhism's core teachings, the law of cause and effect (因果法, pratītyasamutpāda). In the Pali Saṃyutta Nikāya, the Buddha says: "As one sows, so shall one reap. Do good and good fruit comes; do evil and evil fruit comes" (Yādisaṃ vapate bījaṃ, tādisaṃ harate phalaṃ). This principle is not mere moral reward and punishment. In Buddhism, cause and effect (因果) is not a moral verdict but a law of nature. Just as water flows from high ground to low, action (業, karma) automatically gives rise to its result (果, phala). After Buddhism reached China, the idea settled into the four characters 因果應報. It appears in the commentaries to the Selections of Refined Literature (文選) compiled by Crown Prince Zhaoming (昭明太子, 501–531) of the Liang dynasty, and recurs through Buddhist tale collections from the Tang dynasty onward. In Korea, the Goryeo-era National Preceptor Jinul (知訥, 1158–1210) stressed in his Secrets on Cultivating the Mind (修心訣) that "if one does not believe in cause and effect, there is no gateway into practice" (不信因果, 修行無門).
The crux of the phrase lies in the difference between 應 (to answer) and 報 (to repay). 應 means "to respond to a sound," and 報 means "to repay a debt." So the phrase has a double structure: "the cause calls forth the effect (應), and the effect returns to the cause (報)." It is not one-sided punishment but an echo — the sound I cast out coming back to me.
The Western Root — The Goddess of Retribution
The ancient Greek Νέμεσις (Nemesis) derives from the verb νέμειν (nemein, "to distribute, to allot"). Translated literally, it means "the dealing-out of what is due." Nemesis was originally a goddess of Greek myth. In Hesiod's Theogony (c. 700 BCE) she is the daughter of Night (Nyx), the being who carries out the gods' anger against human ὕβρις (hubris, arrogance). At Rhamnous, near Athens, stood a temple of Nemesis, housing a colossal statue made by Agorakritos, a pupil of Pheidias. The word entered English in 1576. According to the OED it was first used as the proper name of the Greek goddess, then broadened from the 17th century into a common noun meaning "inescapable retribution" or "an enemy who carries out retribution." In the 20th century, "nemesis" even took on the popular sense of "arch-enemy" — to Sherlock Holmes, for example, Professor Moriarty is his nemesis.
The core the root νέμειν (to distribute) reveals: Nemesis is not "punishment" but "redistribution." When a human takes more than his own share (hubris), Nemesis comes to restore the original balance. This is strikingly close to the 應 (to answer) of the Eastern phrase. Both are mechanisms not of "punishment" but of "the restoration of balance."

Oxford English Dictionary (OED)"nemesis, n." OED Online. 1576, from Greek Νέμεσις (Nemesis), goddess of retribution, from νέμειν (nemein) "to give what is due, to distribute". Extended sense "agent of retribution or vengeance" from 1600s. Modern sense "inescapable rival or downfall" from 19c.

Online Etymology Dictionaryetymonline.com/word/nemesis — From Greek Nemesis, "goddess of vengeance, retribution," literally "just indignation," from nemein "to give what is due." The transferred sense of "retributive justice" is attested from 1597. Related to Greek nomos "law, custom" (from the same root *nem- "assign, allot").
Shared Wisdom — Balance Is Always Restored
Both define retribution not as "punishment" but as "natural law." The Buddhist law of cause and effect operates automatically, like physics rather than a moral verdict, and Nemesis is not anger but "the redistribution of a deserved share (nemein)." Both traditions strictly distinguish retribution from emotional revenge.
Both stress "inescapability." In Buddhism the fruit of karma is realized without fail, if not in this life then the next, and in Greek tragedy not a single hero ever escaped Nemesis. Both traditions share the conviction that the chain of cause and effect is never broken — it only takes time.
Both are paired with "hubris." The Eastern phrase holds that consequences follow the bad karma (惡業) born of greed and ignorance, and nemesis is a direct response to ὕβρις (arrogance). In that the trigger of retribution is the attempt to take more than one's share, the two concepts are structurally linked.
The difference — the Eastern phrase is a universal law applying to "all actions," while nemesis concentrates especially on retribution for "arrogance and excess." Buddhist cause and effect applies to good karma (善業) as well, but Greek nemesis almost always means only negative consequence. The East looks at "the whole of the seed," the West at "the seed of the poisonous weed."
A Mnemonic — One Line to Take Home
- ✓ 因果應報 = cause (因) and effect (果) answer (應) and repay (報). The law of the echo.
- ✓ nemesis = Greek νέμειν (to distribute) → the goddess who gives back what is due.
- ✓ Remember it at once: "The seed you sow will surely bear fruit, and the goddess will surely come to collect the debt."
"To reap as you sow is not punishment but the law of nature."
