RV 2.12.2
यः पृथिवीं व्यथमानाम् अदृंहद् यः पर्वतान् प्रकुपितां अरम्णात् । यो अन्तरिक्षं विममे वरीयो यो द्याम् अस्तभ्नात् स जनास इन्द्रः ॥
yaḥ pṛthivīṃ vyathamānām adṛṃhad yaḥ parvatān prakupitāṃ aramṇāt | yo antarikṣaṃ vimame varīyo yo dyām astabhnāt sa janāsa indraḥ ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
He who fixed fast and firm the earth that staggered, and set at rest the agitated mountains, Who measured out the air's wide middle region and gave the heaven support, He, men, is Indra.
Translated by Ralph T. H. Griffith (1896)
