bhadrakāpyastu netyāha nahyandho 'andhāt prajāyate /
mātāpitrorapi ca te prāgutpattirna yujyate /
karmajastu mato jantuḥ karmajāstasya cāmayāḥ /
nahṛte karmaṇo janma rogāṇāṃ puruṣasya vā //

Bhadrakāpya, however, said: “That is not so; for a blind person is not born from a blind person; / and even before [the birth of] your mother and father, origin is not logical. / Rather, the living being is considered born of karma, and his diseases are born of karma; / for without karma there is no birth of diseases or of man.”
