Bhagwad Gita
Chapter 14, Verse 16
कर्मणः सुकृतस्याहुः सात्त्विकं निर्मलं फलम्।रजसस्तु फलं दुःखमज्ञानं तमसः फलम्।।14.16।।
By acting in the mode of goodness, one becomes purified. Works done in the mode of passion result in distress, and actions performed in the mode of ignorance result in foolishness.
