PrU 5.4
अथ यदि द्विमात्रेण मनसि संपद्यते । सो ऽन्तरीक्षं यजुर्भिर् उन्नीयते सोमलोकम् । स सोमलोके विभूतिम् अनुभूय पुनर् आवर्तते
atha yadi dvimātreṇa manasi saṃpadyate | so 'ntarīkṣaṃ yajurbhir unnīyate somalokam | sa somaloke vibhūtim anubhūya punar āvartate
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
If he meditate with two Mâtrâs (A+U) he arrives at the Manas, and is led up by the Yagus-verses to the sky, to the Soma-world. Having enjoyed greatness in the Soma-world, he returns again.
