Fruit of three gunas

karmanah sukrtasya huh,sattavicam niralam phalam,
rajasas tu phalam dukham,agnanam tamasah phalam.---16

The fruit of good action is said to be of the nature of goodness and pure and while fruit of passion is pain and the fruit of dullness is ignorance.---16
Swami Ram threeth used to say we get that thing which we give.if we give happiness or love than it will comes to us by happiness or love.If we give hate ,anger, jealously to an other than it also return to us one day.
simply meaning of this solaka is that we harvest that crop which we sow.our good karmas leads to our life towards love,happiness,and if we do bad actions that leads us toward wickedness and pain.
so the fruit of good actions is goodness and pure and fruit of passion is pain and fruit of dullness is ignorance.
