ChU 3.19.2
तद् यद् रजतं सेयं पृथिवी । यत् सुवर्णं सा द्यौः । यज् जरायु ते पर्वताः । यद् उल्बं (स) समेघो नीहारः । या धमनयस् ता नद्यः । यद् वास्तेयम् उदकं स समुद्रः
tad yad rajataṃ seyaṃ pṛthivī | yat suvarṇaṃ sā dyauḥ | yaj jarāyu te parvatāḥ | yad ulbaṃ (sa) samegho nīhāraḥ | yā dhamanayas tā nadyaḥ | yad vāsteyam udakaṃ sa samudraḥ
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
The silver one became this earth, the golden one the sky, the thick membrane (of the white) the mountains, the thin membrane (of the yoke) the mist with the clouds, the small veins the rivers, the fluid the sea.
Translated by F. Max Müller
