What is karma?

In Buddhist thought, karma is not a cosmic ledger that rewards good people and punishes bad ones. It is something more intimate and more mechanical than that. The Pali word "kamma" (Sanskrit: karma) means simply "action," but the Buddha's teaching was precise about which actions count. It is intentional action that generates karma. A stone falling on your foot is not karma in motion. What matters is the volition behind what you do, say, or even think. This places the whole teaching squarely inside your own mind. The Buddha is recorded in the Pali Canon as saying something to the effect that intention is karma, and that understanding sits at the heart of everything else.

The mechanism works like this. Every intentional act leaves a kind of residue, a potential that shapes future experience. Actions rooted in greed, hatred, or delusion tend to produce suffering, both in how the world responds to you and in how your own character solidifies over time. Actions rooted in generosity, compassion, and clarity tend to produce wellbeing and greater freedom. Crucially, the effects are not always immediate and not always obvious, which is part of why karma can feel mysterious or even unjust from the outside. The Theravada tradition, drawing closely on the early Pali texts, maps out karma in considerable detail, distinguishing between karma that ripens quickly, karma that carries forward through this life, and karma whose consequences extend across multiple lifetimes in the Buddhist understanding of rebirth.

What makes this teaching genuinely useful rather than just philosophically interesting is that it shifts your attention away from outcomes you cannot control and toward intentions you can. If you are going through something painful, Buddhism does not ask you to hunt through your past looking for the sin that caused it. That would miss the point entirely. The more immediate question is: what are you doing now, and why? The monk and scholar Bhikkhu Bodhi, who has spent decades translating and explaining the Pali Canon for Western readers, has consistently emphasised that karma is fundamentally a teaching about the formation of character. Each choice you make is also a kind of rehearsal. You become more of what you repeatedly intend.

The Mahayana traditions, which developed later and include schools like Zen and Tibetan Buddhism, carry the basic framework forward but add layers of complexity and, in some respects, a more expansive generosity. The bodhisattva ideal, for instance, involves dedicating the merit generated by your good actions to the benefit of all beings rather than hoarding it for your own liberation. Nagarjuna and the Madhyamaka school also interrogate karma through the lens of emptiness, pointing out that even karmic cause and effect arises dependently and lacks any fixed, inherent existence. This does not dissolve the teaching but deepens it, suggesting that karma is not a thing operating on you from outside, but part of the flowing, interdependent process you already are.

For someone sitting with real difficulty, whether that is regret over past choices, confusion about why life has gone a certain way, or anxiety about what kind of person they are becoming, the Buddhist teaching on karma offers something quite specific. It says that the past is genuinely past. It shaped conditions, yes, but it does not determine what you do next. Every moment of clear, kind, honest intention is planting something new. The tradition does not pretend this is easy or quick. Deeply grooved habits of mind take time and practice to loosen. But the direction of travel is always available, and it begins not with grand gestures but with noticing, as honestly as you can, what is actually motivating you right now.
