4.1.117

na hi karma mahat kiñcit phalaṃ yasya na bhujyate/
kriyāghnāḥ karmajā rogāḥ praśamaṃ yānti tatkṣayāt
atyugraśabdaśravaṇācchravaṇāt sarvaśo na ca /
śabdānāṃ cātihīnānāṃ bhavanti śravaṇājjaḍāḥ//

For there is no great karma whose fruit is not experienced; / diseases born of karma, defying therapy, reach pacification upon its exhaustion. / From hearing an excessively harsh sound, from not hearing at all, / and from hearing exceedingly faint sounds, men become deaf.
