The concept of karma is one of the most general and basic for the philosophical traditions of India, one of an interconnected cluster of concepts that form the basic presuppositions of Indian philosophy. The focus of this essay is on two interrelated aspects of the Buddhist theory of karma. After some preliminary comments on the general philosophical notion of karma and on the enactivist approach to philosophical psychology, I will explore the distinctively Buddhist idea that through the karmic process we enact ourselves—that is, we make and remake ourselves through our actions. Second, I will discuss the idea that we also enact our world(s) through karma—that is, our patterns of action and reaction bring forth meaningful worlds, which in turn shape those very patterns for better or worse. Finally, I will briefly discuss the character and cultivation of enlightened action, action free from the production of karma.
