Anguttaranikaya 1.3.115 Oh meditators, three things are rare to find in the world. Whatever actions they perform, whether good or evil, such will be their inheritance.
Mental volition is the driving force for action at the vocal or physical level.
If this driving force is unwholesome, the vocal and physical actions will be unwholesome. If the seeds are unwholesome, then the fruits are bound to be unwholesome. But if this driving force is wholesome, then the results of the actions are bound to be wholesome. You are nothing but the sum total of your kamma, your sankhara. Whatever you are now, the present reality of this mind-matter structure is nothing but the sum total of and the result of your own accumulated past kamma .
