AVŚ 13.2.28
अतन्द्रो यास्यन् हरितो यद् आस्थाद् द्वे रूपे कृणुते रोचमानः । केतुमान् उद्यन्त् सहमानो रजांसि विश्वा आदित्य प्रवतो वि भासि ॥२८॥
atandro yāsyan harito yad āsthād dve rūpe kṛṇute rocamānaḥ | ketumān udyant sahamāno rajāṃsi viśvā āditya pravato vi bhāsi ||28||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
When, about to go unwearied, he hath approached (ā-sthā) his yellow steeds, he, shining (ruc), makes for himself two forms; rising rich in lights (ketú-), overpowering the dim spaces (rájas), thou illuminest (vi-bhā), O Āditya, all the advances.
Translated by William Dwight Whitney (1905)
