RV 10.45.2
विद्मा ते अग्ने त्रेधा त्रयाणि विद्मा ते धाम विभृता पुरुत्रा । विद्मा ते नाम परमं गुहा यद् विद्मा तम् उत्सं यत आजगन्थ ॥
vidmā te agne tredhā trayāṇi vidmā te dhāma vibhṛtā purutrā | vidmā te nāma paramaṃ guhā yad vidmā tam utsaṃ yata ājagantha ||
Devanagari rendered by HREEM from the edition's roman (IAST) text; the IAST is the edition's own.
Agni, we know thy three powers in three stations, we know thy forms in many a place divided. We know what name supreme thou hast in secret: we know the source from which thou hast proceeded.
Translated by Ralph T. H. Griffith (1896)
