PrU 5.6
तिस्रो मात्रा मृत्युमत्यः प्रयुक्ता अन्योन्यसक्ता अनविप्रयुक्ताः । क्रियासु बाह्याभ्यन्तरमध्यमासु सम्यक्प्रयुक्तासु न कम्पते ज्ञः
tisro mātrā mṛtyumatyaḥ prayuktā anyonyasaktā anaviprayuktāḥ / kriyāsu bāhyābhyantaramadhyamāsu samyakprayuktāsu na kampate jñaḥ
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The three Mâtrâs (A+U+M), if employed separate, and only joined one to another, are mortal; but in acts, external, internal, or intermediate, if well performed, the sage trembles not.
Translated by F. Max Müller
