Verse 14.16
कर्मणः सुकृतस्याहुः सात्त्विकं निर्मलं फलम् । रजसस्तु फलं दुःखमज्ञानं तमसः फलम् ॥ १४.१६ ॥
श्रेष्ठ कर्म का तो सात्विक अर्थात् सुख, ज्ञान और वैराग्यादि निर्मल फल कहा है ; राजस कर्म का फल दुःख एवं तामस कर्म का फल अज्ञान कहा है ।
The purity of SATTVA is characterized by the rewards that come out of good actions. However, the fruits of work that is done in the RAJAS state brings nothing but pain to a person; and work that is done in the TAMAS state, bears fruits of dullness and ignorance.
