Wisdom from the Heart : Joyous Perseverance in good deeds.

15. The evil-doer grieves here and hereafter; he grieves in both the worlds. He laments and is afflicted, recollecting his own impure deeds.

16. The doer of good rejoices here and hereafter; he rejoices in both the worlds. He rejoices and exults, recollecting his own pure deeds.

17. The evil-doer suffers here and hereafter; he suffers in both the worlds. The thought, “Evil have I done,” torments him, and he suffers even more when gone to realms of woe.

18. The doer of good delights here and hereafter; he delights in both the worlds. The thought, “Good have I done,” delights him, and he delights even more when gone to realms of bliss.
