4 Kammas
Four kinds of kamma:
- There is dark kamma with dark ripening
- There is bright kamma with bright ripening
- There is dark-and-bright kamma with dark-and-bright ripening
- There is kamma that is not dark and not bright with neither-dark-nor-bright ripening that conduces to the exhaustion of kamma
(Majjhima Nikaya 57, Anguttara Nikaya 4.235)
