What Is Karma? What Buddhism Actually Teaches

Karma (Sanskrit; in Pali, kamma) means "action". In Buddhism it refers specifically to intentional action, meaning what you do, say or think on purpose, along with the results that follow. It is not fate, and it is not a cosmic system of reward and punishment. The early texts treat it as a matter of intention shaping experience. Later Mahayana and Tibetan traditions add their own detail, which this article labels as it goes.

Karma means intentional action

Early Buddhism / Theravada (Pali canon).

The most direct definition comes from the Nibbedhika Sutta (Anguttara Nikaya 6.63), in Thanissaro Bhikkhu's translation: "Intention, I tell you, is kamma." The point is easy to miss. Karma is not the event that happens to you, and it is not even the physical act on its own. It is the intention behind what you do.

The same sutta describes three channels for that intention: body, speech and intellect (many teachers simply say "mind"). You can act on a wish with your hands, with words, or only in thought. Each counts. That is why two identical actions can have different weight. Handing someone a glass of water because you want to help and handing it over to win a favour are the same movement with different intentions.

This makes karma less like a ledger kept by someone else and more like a description of how your own habits form. What you intend, again and again, shapes how you see, react and choose.

How it works: a natural law, not a judge

Early Buddhism / Theravada.

In the Buddhist account, no deity hands out outcomes. Karma is described as a process, closer to cause and effect than to a court. Intentional actions have consequences, and those consequences feed back into your next intentions. Thanissaro Bhikkhu's essay on karma speaks of this in terms of feedback loops, where present choices and present experience keep shaping each other.

Teachers often place karma as one strand among several natural processes. Lion's Roar mentions a scheme of five natural orders (niyamas), with karma as one of the five. That already tells you something: karma is not the only thing that explains why things happen.

What karma is not

Early Buddhism / Theravada.

Not everything you feel is caused by past action. In the Sivaka Sutta (Samyutta Nikaya 36.21), the Buddha rejects the view that whatever a person feels is entirely caused by what was done before. The sutta lists other sources of pain and discomfort, including bile disorders and changes of weather. This is a useful corrective to the pop idea that every misfortune is a bill coming due. One caution: the translator's note reads the sutta as saying that karma works within other causal factors, and that many of those factors may themselves be linked to past action. Karma is one strand, not the whole story and not nothing.

Not fatalism. The Tittha Sutta (Anguttara Nikaya 3.61) criticises the view that everything a person experiences is caused by past deeds. Its argument is that someone who falls back on the past as the whole explanation has no reason to make an effort. Thanissaro Bhikkhu's essay "Karma" makes a related general point: karma works through feedback loops, so present choices count, even though their range is shaped by the past. Your present intention is part of the picture, and it can be shaped.

Not victim-blaming. This is our reading of the texts above rather than an explicit statement in them. Since the early texts do not teach that every misfortune is deserved, an illness, a loss or an injustice is not proof that someone earned it. If you have heard "you must have done something to cause this", be wary of it.

Can karma change?

Early Buddhism / Theravada.

Yes, and the Lonaphala Sutta (Anguttara Nikaya 3.99), "The Salt Crystal", is the classic text on this. Its image is familiar: a lump of salt dropped into a small cup of water makes the water undrinkable, while the same lump dropped into a large river changes nothing. In the sutta's teaching, the same trifling unskillful act weighs differently depending on the person. Someone undeveloped in body, virtue, mind and discernment feels the result heavily; the sutta's own contrast is stark, and it is framed in terms of rebirth. Someone developed in those ways feels it in the here and now, and it barely registers.

The practical lesson is that the past does not fix the future. What you cultivate now changes how any given action lands.

Mahayana and Tibetan view: imprints and seeds

Mahayana / Tibetan. This section describes later developments, not the early texts.

Mahayana and Tibetan Buddhism keep the early definition and add more machinery.

Four aspects of a complete action. In the standard Tibetan lamrim ("stages of the path") teaching, which goes back to Tsongkhapa's synthesis of earlier Indian sources, a complete karmic action has four factors: a basis or object, an intention (the motivating state of mind), the action itself, and its completion. Modern teachers such as Thubten Zopa Rinpoche present the same framework. It is useful for ordinary reflection: ask toward whom you acted, why, what you actually did, and whether you carried it through.

Imprints and seeds. Actions are said to leave imprints on the mind, often described with the image of seeds that ripen when conditions allow. Seed imagery is not purely a later idea. In the Bhava Sutta (Anguttara Nikaya 3.77), the Buddha says kamma is the field, consciousness the seed and craving the moisture. What the Yogacara school added is a worked-out model: imprints are said to be held in the alaya-vijnana, often translated as the "storehouse consciousness". That storehouse model is a Mahayana development and does not appear in Theravada.

Ten non-virtues. Tibetan texts organise unskillful action into a list of ten non-virtues across body, speech and mind. Patrul Rinpoche's The Words of My Perfect Teacher is the classic text where students meet this material in detail.

A loose parallel for everyday readers: a habit of kindness is like a seed you water, and a habit of irritation is like one you water too. This is an image, not a measurement.

Practice: a five-minute intention check

Works across traditions as a reflection exercise. The final step draws on the Mahayana habit of dedication.

You do not need to accept any doctrine to try this. It simply puts the central idea, that intention matters, into your day.

Morning (one minute). Before you start, pick one intention for the day. Keep it small and concrete: "I will listen without interrupting in my next meeting", or "I will be patient when I am tired." Say it silently or write it down.

Evening (four minutes).

1. Recall one act. Choose one thing you did today, large or small.
2. Ask about the motivation. What was the intention underneath? Were you helping, avoiding, proving something, or just reacting? Stay honest and gentle. This is observation, not a trial.
3. Notice the result. What did that intention seem to produce, in you or in the other person?
4. Dedicate. If the act was wholesome, take a moment to be glad about it, then direct its good toward someone: "May this be of benefit to others." If it was not, name what you would do differently and set the intention for tomorrow. The wider practice is described in our guide to dedication of merit. If you want a calm place to do the evening check, how to meditate covers the basics. For the broader framework karma sits in, see the Four Noble Truths.

Rejoy is a practice-support app, not a source of Buddhist authority. After a session you can record a short dedication by voice or text, which matches the evening step above: pausing to name what you did and who it is for. Over time you can look back on why each session mattered. The seeds in the app track time and practice, not karma itself, and the app does not predict outcomes. It is a place to keep the habit.

Common questions

Is karma the same as fate? No. In the early texts, karma is intentional action and its results, and the Tittha Sutta criticises the view that everything is explained by past deeds. Your present intentions matter.

Does karma explain disasters or illness? Not by itself. The Sivaka Sutta says that not everything a person feels comes from past action, and names other sources of pain, such as bile disorders and weather. Karma is one factor, not a universal explanation, though the tradition discusses how those other factors relate to it.

Is there "good karma" and "bad karma"? The early texts speak of skillful and unskillful action, based on the intention behind it. The popular terms are shorthand. They are best read as "action rooted in care" versus "action rooted in harm or confusion", not as points on a scoreboard.

Do I have to believe in rebirth to use this? Rebirth is part of the traditional framework in which karma is taught, and the traditions covered here include it. Modern teachers and practitioners differ on how they relate to it, and this article does not take a side. You can try the intention check above without settling the question.
