Yoga sutra 2.14
te hlāda-paritāpa-phalāḥ puṇya-apuṇya-hetutvāt
The fruits of our state of mind during the three domains of experience (action, the length of the action and the experience of the action) cause either joy or pain depending on whether the intention was noble or corrupt.
Fortunately, not all of the fruits of our actions come from afflictions (kleśa); “karma” works both ways: The fruits (phalāḥ) of the three domains of experience cause (hetutvāt) either joy (hlāda) or pain (paritāpa) depending on whether the intention was noble (puṇya) or corrupt (apuṇya). Therefore, when goodness inspires your conduct, the results are sweet and happy.
