  The Sanskrit term karma literally means ‘action’. What is nowadays referred to somewhat loosely as the theory of karma is, speaking more strictly, the view that there is a causal relationship between action (karma) and ‘fruit’ (phala), the latter being an experience of pleasure, pain or indifference for the agent of the action. This is the view that the Buddha appears to have accepted in its most straightforward form. Actions are said to be of three types: bodily, verbal and mental. The Buddha insists, however, that by action is meant not the movement or change involved, but rather the volition or intention that brought about the change. As Gombrich (2009) points out, the Buddha’s insistence on this point reflects the transition from an earlier ritualistic view of action to a view that brings action within the purview of ethics. For it is when actions are seen as subject to moral assessment that intention becomes relevant. One does not, for instance, perform the morally blameworthy action of speaking insultingly to an elder just by making sounds that approximate to the pronunciation of profanities in the presence of an elder; parrots and prelinguistic children can do as much. What matters for moral assessment is the mental state (if any) that produced the bodily, verbal or mental change. And it is the occurrence of these mental states that is said to cause the subsequent occurrence of hedonically good, bad and neutral experiences. More specifically, it is the occurrence of the three ‘defiled’ mental states that brings about karmic fruit. The three defilements (kleśas) are desire, aversion and ignorance. And we are told quite specifically (A III.33) that actions performed by an agent in whom these three defilements have been destroyed do not have karmic consequences; such an agent is experiencing their last birth.
