Bhashya
अथ यद्येनमूष्मसु तथैवोपालभेत, प्रजापतिं शरण प्रप-न्नोऽभूवम्, स त्वा प्रति पेक्ष्यति सचूर्णयिष्यतीत्येन ब्रूयात् ।अथ यद्येन स्पर्शेषूपालभेत, मृत्यु शरण प्रपन्नोऽभूवम, सत्वा प्रति धक्ष्यति भस्मीकरिष्यतीत्येन ब्रूयात् ॥
In plain words
Now, if someone should similarly criticize him regarding the sibilants, he should tell him: 'I have taken refuge in Prajāpati; he will look upon you and crush you to pieces.' And if someone should criticize him regarding the stop consonants, he should tell him: 'I have taken refuge in Death; he will burn you and reduce you to ashes.'
Close to the Sanskrit
Now if in sibilants thus indeed one should criticize, 'Prajāpati refuge approached I became, he thee back will regard and pulverize,' thus to him one should speak; now if in stops one should criticize, 'Death refuge approached I became, he thee back will burn and reduce to ashes,' thus to him one should speak.
