CHĀNDOGYA UPANISHAD · 2.22.4

अथ यद्य् एनम् ऊष्मासूपालभेत ।
प्रजापतिं शरणं प्रपन्नो ऽभूवं स त्वा प्रति पेक्ष्यतीत्य् एनं ब्रूयात् ।
अथ यद्य् एनं स्पर्शेषूपालभेत ।
मृत्युं शरणं प्रपन्नो ऽभूवं स त्वा प्रति धक्ष्यतीत्य् एनं ब्रूयात् ॥

atha yady enam ūṣmāsūpālabheta ।
prajāpatiṃ śaraṇaṃ prapanno ’bhūvaṃ sa tvā prati pekṣyatīty enaṃ brūyāt ।
atha yady enaṃ sparśeṣūpālabheta ।
mṛtyuṃ śaraṇaṃ prapanno ’bhūvaṃ sa tvā prati dhakṣyatīty enaṃ brūyāt ॥

And if somebody should reprove him for his sibilants, let him say, 'I went to Pragâpati as my refuge: he will smash thee.' And if somebody should reprove him for his consonants, let him say, 'I went to Mrityu as my refuge: he will reduce thee to ashes.'
