The Pali word kamma (the more commonly known term is the Sanskrit karma) means ‘action’ and in Buddhist doctrine refers to any intentional mental, verbal or bodily act. The Buddha says, ‘I say that intention is kamma, because having first intended one acts with body, speech or mind’ (A.III,415) According to the Buddha, every intentional action modifies our consciousness, thus building our character and thereby influencing our behaviour, our experience and consequently our destiny. Positive intentional actions (motivated by generosity, love and wisdom) tend towards consequences that are experienced as positive while intentional negative actions (motivated by greed, hatred and ignorance) tend towards consequences that are experienced as negative.

The doctrine of kamma is probably the most misunderstood of all the Buddha’s teachings. The four most common misunderstandings are these.

Because kamma is primarily psychological (i.e. intention), its manifestation is primarily psychological. It only affects our physical form and circumstances to the degree that the mind can have an influence on the physical, as for example when prolonged worry can cause physical illness. The main effect kamma has upon us is how we feel (happy, neutral or unhappy) and which realm we will be reborn into.

The arahant, the liberated one, does not generate any more kamma. He continues to act and perform volitional actions, but without clinging. Hence his actions no longer constitute kamma. They don't leave any imprints upon the mind. They don't have the potency of ripening in the future to bring about rebirth. The activities of the arahants are called “Kriyas”, not kammas. They are simple actions. They leave no trace on the mental continuum, just like the flight of birds across the sky.
