Here one joys, one joys hereafter,
in both ways does the merit-maker joy;
one joys and one rejoices,
one's own pure kammas seeing.
-Dhammapada Verse 16
Explanation: A wise person does good deeds. Having done those good deeds he rejoices here in this world. He rejoices in the life after as well. Seeing the purity of his virtuous actions, he rejoices. He is thoroughly joyous seeing the goodness of his deeds.
