सहस्राह्ण्यं वियताव् अस्य पक्षौ हरेर् हंसस्य पततः स्वर्गम् । स देवान्त् सर्वान् उरस्य् उपदद्य संपश्यन् याति भुवनानि विश्वा ॥१८॥
sahasrāhṇyaṃ viyatāv asya pakṣau harer haṃsasya patataḥ svargam | sa devānt sarvān urasy upadadya saṃpaśyan yāti bhuvanāni viśvā ||18||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
A thousand days' journey [are] expanded (vi-yam) the wings of him, of the yellow swan flying to heaven (svargá); he, putting all the gods in his breast, goes, viewing together all existences.
Translated by William Dwight Whitney (1905)
