PRAŚNA UPANISHAD · 5.4

अथ यदि द्विमात्रेण मनसि सम्पद्यते सोऽन्तरिक्षं
यजुर्भिरुन्नीयते सोमलोकम् । स सोमलोके विभूतिमनुभूय
पुनरावर्तते ॥ ५.४॥

atha yadi dvimātreṇa manasi sampadyate so’ntarikṣaṃ
yajurbhirunnīyate somalokam । sa somaloke vibhūtimanubhūya
punarāvartate ॥ 5.4॥

“Now if by the two letters of the syllable he in the mind attaineth, to the skies he is exalted and the hymns of the Yajur escort him to the Lunar World. In the heavens of the Moon he feeleth his soul’s majesty; then once more he returneth.

Sri Aurobindo · CWSA 18, p. 188
