na sādhu-vādo muni-kopa-bharjitā
nṛpendra-putrā iti sattva-dhāmani
kathaṁ tamo roṣamayaṁ vibhāvyate
jagat-pavitrātmani khe rajo bhuvaḥ
na—not; sādhu-vādaḥ—the opinion of learned persons; muni-kopa—by the anger of Kapila Muni; bharjitāḥ—were burned to ashes; nṛpendra-putrāḥ—all the sons of Sagara Mahārāja; iti—thus; sattva-dhāmani—in Kapila Muni, in whom the mode of goodness was predominant; katham—how; tamaḥ—the mode of ignorance; roṣa-mayam—manifested in the form of anger; vibhāvyate—can be manifested; jagat-pavitra-ātmani—in He whose body can purify the whole world; khe—in the sky; rajaḥ—dust; bhuvaḥ—earthly.
It is sometimes argued that the sons of King Sagara were burned to ashes by the fire emanating from the eyes of Kapila Muni. This statement, however, is not approved by great learned persons, for Kapila Muni’s body is completely in the mode of goodness and therefore cannot manifest the mode of ignorance in the form of anger, just as the pure sky cannot be polluted by the dust of the earth.
