Dhammapada verses 17 and 18

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.
