कर्मणः सुकृतस्याहुः सात्त्विकं निर्मलं फलम्।
रजसस्तु फलं दुःखमज्ञानं तमसः फलम्।।14.16।।
14.16 They say that the result of good work is pure and is born of sattva. But the result of rajas is sorrow; the result of tamas is ignorance.
14.16 Thus, the fruit of a good deed, namely, disinterested work in the form of My worship, performed by one who dies when Sattva prevails - is birth in the family of those who know the self. There he acires more Sattva than before and the self becomes more pure, namely, devoid of the slightest vestige of suffering. So say those who know about the development of Sattva. But the fruit of Rajas, dominating at the time of death, is suffering in Samsara. In consists in successive births in families attached to actions for the sake of fruits. Rirth of this type increases Rajas further, resulting in actions for gaining their fruits. So say those who know about the developments of this Guna. Ignorance is the result of Tamas. The fruit of Tamas dominating at the time of death, is successive conditions of ignorance. What are the results derived from Sattva etc.? To this, He answers:
Karmanah sukritasyaahuh saattwikam nirmalam phalam; Rajasastu phalam duhkham ajnaanam tamasah phalam.
