What is karma in buddhism ?

Karma

Volition, volitional or intentional activity.



Karma is always followed by its fruit, Vipaka. Karma and Vipaka are oftentimes referred to as the law of causality, a cardinal concern in the Teaching of the Buddha.



* Common karma: the difference between personal and common karma can be seen in the following example: Suppose a country goes to war to gain certain economic advantages and in the process, numerous soldiers and civilians are killed or maimed. If a particular citizen volunteers for military service and actually participates in the carnage, he commits a personal karma of killing. Other citizens, however, even if opposed to the war, may benefit directly or indirectly (e.g., through economic gain). They are thus said to share in the common karma of killing of their country.



* Fixed karma: in principle, all karma is subject to change. Fixed karma, however, is karma which can only be changed in extraordinary circumstances, because it derives from an evil act committed simultaneously with mind, speech and body. An example of fixed karma would be a premeditated crime (versus a crime of passion).
