PrU 5.3
स यद्य् एकमात्रम् अभिध्यायीत । स तेनैव संवेदितस् तूर्णम् एव जगत्याम् अभिसम्पद्यते । तम् ऋचो मनुष्यलोकम् उपनयन्ते । स तत्र तपसा ब्रह्मचर्येण श्रद्धया सम्पन्नो महिमानम् अनुभवति
sa yady ekamātram abhidhyāyīta | sa tenaiva saṃveditas tūrṇam eva jagatyām abhisampadyate | tam ṛco manuṣyalokam upanayante | sa tatra tapasā brahmacaryeṇa śraddhayā sampanno mahimānam anubhavati
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
If he meditate on one Mâtrâ (the A), then, being enlightened by that only, he arrives quickly at the earth. The Rik-verses lead him to the world of men, and being endowed there with penance, abstinence, and faith, he enjoys greatness.
