Karma is the universal causal law, found in Hinduism, Buddhism and Jainism, by which a person’s intentional actions determine the conditions of their future existence, including future rebirths. The word derives from the Sanskrit karman, meaning act. Its ethical dimension is inseparable from the cycle of rebirth known as samsara, and release from that cycle is the shared soteriological goal of the Indian religious traditions that accept the doctrine.

The Meaning of the Word and the Basic Concept
The English word karma is a direct borrowing from Sanskrit. The Sanskrit term karman carries the straightforward, literal sense of act or deed. In its passage into religious and philosophical thought, the word accumulated a much richer burden of meaning: not merely any act, but every intentional act understood as a cause that will produce morally weighted effects, in this life or in lives yet to come.
The basic claim of the karma doctrine is causal and moral at once. Good actions generate good karmic residue; harmful actions generate bad karmic residue. That residue shapes the conditions under which a person continues to exist, whether by influencing their circumstances within the present life or, more fundamentally, by determining the nature of their next rebirth. The scale of the mechanism is therefore cosmic, operating across multiple lifetimes rather than within the narrow frame of a single biography.
Two further concepts are structurally linked to karma and cannot be understood in isolation from it. The first is samsara, the cycle of rebirth or transmigration through which beings pass repeatedly. The second is moksha, a Sanskrit term usually translated as liberation or release, referring to the final escape from that cycle. Karma is, in this framework, the engine that keeps beings turning within samsara: accumulated karma binds a being to continued rebirth, while the exhaustion or avoidance of karma is the mechanism by which liberation becomes possible. The desire to attain moksha is what gives the karma doctrine its motivational force for moral life.
Origins: The Upanishads and the First Millennium BCE
The earliest evidence for karma understood in its ethical, morally causal sense comes from the Upanishads, a body of philosophical and speculative texts that belong to the middle of the first millennium BCE. This date places the emergence of the doctrine’s ethical meaning in roughly the same historical period as the founding of Buddhism and Jainism, and scholars regard the mid-first millennium BCE as a formative era for Indian religious and philosophical thought more broadly.
Before the Upanishads, the word karman appeared in the Vedic literature primarily in a ritual sense, referring to the performance of sacred rites. The moral and metaphysical transformation of the concept, linking personal action to personal destiny across rebirths, represents a significant development in Indian intellectual history. The Upanishads moved attention inward, towards the nature of the self and its relationship to ultimate reality, and within that inward turn the idea that a person’s deeds shape their future existence found its natural home.
It is worth being precise here: the Upanishads did not invent the concept of rebirth, which had earlier roots in Indian thought. What the Upanishads contributed most clearly was the systematic ethical dimension, the idea that it is the moral quality of actions, rather than simply the correct performance of ritual, that governs the trajectory of a being’s existence across successive lives.
How the Three Main Traditions Understand Karma
Although karma is a shared concept across Hinduism, Buddhism and Jainism, each tradition understands it in ways that reflect its own deeper commitments about the self, reality and liberation. The differences are philosophically significant.
Hinduism
Within the Hindu traditions, karma functions as the universal law by which good or bad actions determine future modes of existence. The self that accumulates karma and passes through successive rebirths is typically understood as a real, enduring entity. In many Hindu philosophical schools, this self, often called the atman, is genuine and persistent, transmigrating from one body to another while carrying its karmic inheritance. The goal of liberation, moksha, involves the recognition of or union with ultimate reality, and the release from the karmic cycle that this brings about.
Karma in Hindu thought also carries an explanatory function in relation to social circumstance. The conditions into which a person is born, their health, their prosperity, their social position, are understood within this framework as reflecting the karmic consequences of actions in previous lives. This explanatory use of karma is simultaneously one of the doctrine’s most socially significant features and one of its most contested.
Buddhism
Buddhism accepts the karma doctrine as central to its account of moral life and rebirth, but modifies it in a philosophically striking way. The Buddhist doctrine of anatta, commonly translated as non-self, denies that there is any permanent, unchanging soul or self underlying experience. For Buddhism, what we ordinarily call a person is a flowing process of physical and mental events, not a fixed entity.
This creates a distinctive philosophical puzzle: if there is no permanent self, what exactly is it that is reborn, and what carries karma from one life to the next? Buddhism addresses this by speaking of a causal continuum rather than a transmigrating soul. Rebirth in Buddhism is not the passing on of an unchanging self but the continuation of a causally connected process, in something like the way that one flame can light another without the second flame being identical to the first. Karma, in this scheme, is generated by intentional mental acts above all: it is the intention behind an action that carries moral weight.
Buddhism also emphasises the role of karma in motivating ethical conduct. Living well, practising compassion, avoiding harm and cultivating wisdom are all understood as ways of generating favourable karma and moving towards the ultimate Buddhist goal of nirvana, the cessation of craving and the escape from the cycle of rebirth.
Jainism
Jainism, which also emerged around the middle of the first millennium BCE, gives the karma doctrine a particularly elaborate and physicalist treatment. Jain philosophy conceives of karma not merely as a moral or causal principle but as an actual subtle matter that adheres to the soul as a result of actions, thoughts and speech. The accumulation of this karmic matter is what keeps the soul bound within samsara.
Jainism is notable for the exceptional rigour with which it pursues the avoidance of harm, ahimsa, as the primary means of preventing new karmic accumulation. The Jain tradition holds that every living being, however small, possesses a soul, and that causing harm to any living being generates negative karma. This conviction drives the strict ethical practices, including vegetarianism and extraordinary care not to injure even insects, for which Jain ascetic communities are known. Liberation in Jainism means the complete removal of karmic matter from the soul, allowing it to rise to the highest realm of the universe in a state of pure consciousness.
Karma’s Moral Functions: Motivation and Explanation
The karma doctrine performs two distinct and important moral functions within the traditions that hold it. The first is motivational: it provides a systematic reason to act well and avoid harm. If every intentional action has proportionate moral consequences that will inevitably be experienced, by the same person in a future life if not in this one, the incentive to live ethically is built into the structure of reality itself. The good person is not simply admirable; they are, by the logic of karma, also prudent. Cruelty and dishonesty will, over the arc of multiple lifetimes, return to the agent. Generosity and compassion will similarly bear future fruit.
The second function is explanatory. Karma serves as the primary explanation of the existence of evil and suffering in Indian moral philosophy. A person’s present circumstances, including their suffering, their disabilities, their social disadvantage, are understood as the karmic inheritance of past actions. This explanation has the apparent advantage of making suffering intelligible and of avoiding the conclusion that suffering is random or unjust. Within the karma framework, there is no genuinely innocent sufferer in an ultimate sense: suffering is always the working out of prior causes.
This explanatory function intersects with broader questions about how religious worldviews account for suffering and moral evil, questions explored in discussions of religion, suffering and the afterlife. The karma-based explanation differs substantially from the theodicy traditions developed in Western monotheisms, though it addresses a recognisably similar challenge: how to make moral sense of suffering within a universe governed by moral principles.
The Popular Western Sense and How It Differs
In contemporary Western popular culture, karma has acquired a meaning that is related to but considerably thinner than its traditional doctrinal sense. In everyday speech, karma typically refers to a kind of cosmic fairness operating within a single lifetime: the person who behaves badly will, sooner or later, experience bad consequences; the person who acts kindly will find good things coming their way. The phrase “what goes around comes around” captures the popular sense fairly well.
This popular usage strips away several features that are essential to karma’s meaning in its source traditions. It removes rebirth entirely: the popular Western concept operates within one life, not across multiple existences. It removes the specific philosophical frameworks, the Hindu conception of the atman, the Buddhist doctrine of anatta, the Jain account of karmic matter, that give the doctrine its content. It also typically removes the soteriological goal of release from samsara, which gives the doctrine its motivational urgency within the traditions themselves.
The result is a secularised intuition about cosmic fairness rather than a metaphysical doctrine about the moral structure of existence across lifetimes. Many people who invoke karma in this casual sense have no commitment to rebirth and no interest in moksha or nirvana. They are expressing a moral hope, that bad behaviour will be punished and good behaviour rewarded, rather than asserting a belief in the full doctrinal package that the word originally carried.
Main Criticisms of the Karma Doctrine
Several serious philosophical objections are raised against the karma doctrine, particularly by secular critics and within the analytic philosophy of religion. Two stand out as the most fundamental.
The first is what might be called the problem of apparently innocent suffering. The karma doctrine is offered, in part, as an explanation of why people suffer: they suffer because of their own past actions. But this explanation faces a significant moral challenge. When children suffer from disease or natural disaster, when entire populations are devastated by events that bear no plausible relationship to their individual actions, the claim that their suffering reflects their own prior karma can seem both unfalsifiable and morally troubling. It risks functioning as a rationalisation for indifference to injustice: if the sufferer’s condition is their own karmic inheritance, the urgency to intervene or reform unjust social arrangements may be diminished. Critics argue that the karma explanation, applied to social suffering, can serve as an ideological prop for acceptance of conditions that might otherwise be challenged.
This tension between karma-based explanations of suffering and other frameworks for understanding moral evil connects to broader discussions in the philosophy of religion, including those surrounding the evil god challenge and theodicy. While the karma doctrine offers a different kind of answer than Western theodicy, it faces analogous pressure to account coherently for suffering that appears disproportionate or inexplicable.
The second major criticism concerns the empirical basis for the doctrine’s central claim. Karma, as traditionally understood, requires that there be future rebirths in which karmic consequences are experienced. It further requires some mechanism by which karmic residue is preserved and transmitted across the gap between one life and the next. Neither the existence of rebirth nor the existence of any such transmission mechanism has been established by evidence that meets ordinary scientific standards. Secular critics therefore argue that the karma doctrine, while morally interesting and psychologically compelling, rests on an empirical claim, that beings are reborn and that moral causation extends across lifetimes, for which there is no satisfactory evidence.
A related criticism is that the doctrine is structured in a way that makes it very difficult to test or falsify. Because karmic causes can in principle reach back through an unlimited number of previous lives, any present circumstance can always be attributed to some prior action whose details are beyond examination. This explanatory flexibility, while it makes the doctrine comprehensive, also insulates it from empirical challenge in a way that many critics find unsatisfying.
Defenders of the karma doctrine respond to these objections in various ways. Some argue that the doctrine, properly understood, does not counsel passivity in the face of suffering but rather motivates compassionate action, since generating good karma involves acting generously and reducing harm. Others argue that the absence of scientific evidence for rebirth does not settle the question, since the methods of empirical science may not be the appropriate tools for evaluating claims about the nature of consciousness and its continuity across lives. These responses are seriously offered within the traditions, and the debate remains unresolved.
FAQ
What does the word karma literally mean?
Karma comes from the Sanskrit word karman, which means act or deed. In its religious and philosophical use, it refers specifically to the moral weight carried by intentional actions and the causal consequences those actions produce in future existence.
Is karma the same in Hinduism, Buddhism and Jainism?
The three traditions share the core idea that intentional actions produce morally weighted consequences affecting future existence, but they differ substantially in their philosophical frameworks. Hinduism typically posits a real transmigrating self; Buddhism denies any permanent self, so rebirth involves a causal continuum rather than a travelling soul; Jainism treats karma as subtle matter that physically adheres to the soul. The traditions also differ in how liberation from the karmic cycle is achieved.
When did the ethical meaning of karma first appear?
The earliest evidence for karma’s ethical meaning, linking personal actions to future rebirths rather than to ritual efficacy, comes from the Upanishads, texts that belong to the middle of the first millennium BCE. Buddhism and Jainism, which developed the concept further, also emerged around the same period.
How does the popular Western use of karma differ from its traditional meaning?
The popular Western sense treats karma as a kind of cosmic fairness operating within a single lifetime, with no commitment to rebirth, the transmigrating self or the goal of liberation from samsara. Traditional karma is a metaphysical doctrine about the moral structure of existence across multiple lives, inseparable from the broader framework of samsara and moksha.
What are the main philosophical objections to karma?
Two objections stand out. First, the doctrine explains suffering by attributing it to the sufferer’s own past actions, which critics argue can rationalise indifference to injustice and seems morally troubling in cases of apparently innocent victims such as young children. Second, the doctrine’s core claim, that moral consequences carry over across rebirths, relies on the existence of rebirth, for which no satisfactory scientific evidence has been produced. Critics also note that the doctrine’s explanatory flexibility makes it very difficult to test empirically.
Does believing in karma make someone passive about suffering?
Critics have raised this concern, arguing that the karma explanation of suffering may encourage acceptance of unjust conditions. Defenders within the traditions counter that karma also motivates compassionate action, since helping others and reducing harm generates positive karma. Whether the doctrine in practice encourages or discourages social reform is a matter of ongoing discussion among scholars and practitioners alike.
Summary
Karma is, at its core, the doctrine that intentional actions carry a moral weight that shapes the conditions of a being’s future existence, including future rebirths within the cycle of samsara. The word derives from the Sanskrit karman, meaning act, and its ethical meaning is first clearly attested in the Upanishads in the middle of the first millennium BCE. Buddhism and Jainism, which emerged around the same time, developed the concept in distinctive ways: Buddhism denies any permanent self underlying the karmic process, while Jainism conceives of karma as subtle matter adhering physically to the soul.
Within all three traditions, karma performs two key moral functions: it provides the primary motivation for ethical conduct, since harmful actions will inevitably return to affect the agent in future lives, and it serves as the principal explanation of suffering, understood as the working out of prior karmic causes. The popular Western sense of karma, as a kind of one-lifetime cosmic fairness, retains the intuition about moral cause and effect but strips away the rebirth framework and the soteriological context that give the traditional doctrine its full meaning.
The main philosophical criticisms of karma concern its moral implications for understanding innocent suffering and the absence of evidence for the rebirth on which the doctrine depends. These criticisms are taken seriously by secular philosophers, while defenders within the traditions offer responses that keep the debate genuinely open. Understanding what karma actually means in its traditional context, rather than in its diluted popular form, is a necessary first step for any serious engagement with these questions.
