17. The evil-doer suffers in this world, and he suffers in the next; he suffers in both. He suffers when he thinks of the evil he has done; he suffers more when going on the evil path.
18. The virtuous man is happy in this world, and he is happy in the next; he is happy in both. He is happy when he thinks of the good he has done; he is still more happy when going on the good path.
DHAMMAPADA, Chapter 1. The Twin Verses
