The Buddha describes the four kinds of kamma (actions) and their results in brief.
“Cattārimāni, bhikkhave, kammāni mayā sayaṁ abhiññā sacchikatvā paveditāni. Katamāni cattāri?
“Bhikkhus, there are these four kinds of |kamma::actions, deeds [kammā]| proclaimed by me after having realized them for myself through direct knowledge. What four?
Atthi, bhikkhave, kammaṁ kaṇhaṁ kaṇhavipākaṁ;
atthi, bhikkhave, kammaṁ sukkaṁ sukkavipākaṁ;
atthi, bhikkhave, kammaṁ kaṇhasukkaṁ kaṇhasukkavipākaṁ;
atthi, bhikkhave, kammaṁ akaṇhaasukkaṁ akaṇhaasukkavipākaṁ kammakkhayāya saṁvattati.
Imāni kho, bhikkhave, cattāri kammāni mayā sayaṁ abhiññā sacchikatvā paveditānī”ti.
1.) There is, bhikkhus, kamma that is dark |with dark results::having negative consequences [kaṇhavipāka]|;
2.) There is, bhikkhus, kamma that is bright |with bright results::with positive consequences [sukkavipāka]|;
3.) There is, bhikkhus, kamma that is dark and bright |with dark and bright results::with both positive and negative consequences [kaṇhasukkavipāka]|;
4.) There is, bhikkhus, kamma that is neither dark nor bright with neither dark nor bright result, which leads to the |exhaustion of kamma::wearing away of actions [kammakkhaya]|.
These, bhikkhus, are the four kinds of kamma proclaimed by me after having realized them for myself through direct knowledge.”
