Bhagavad Gita 14.16

कर्मण: सुकृतस्याहु: सात्विकं निर्मलं फलम् |
राजसस्तु फलं दु:खमज्ञानं तमस: फलम्

Translation

It is said the fruit of actions performed in the mode of goodness bestow pure results. Actions done in the mode of passion result in pain, while those performed in the mode of ignorance result in darkness.
