2.6.1

sámās tvāgna r̥távo vardhayantu saṃvatsarā́ ŕ̥ṣayo yā́ni satyā́ |
sáṃ divyéna dīdihi rocanéna víśvā ā́ māhi pradíśaś cátasraḥ ||1||

Let the summers (sámā), O Agni, the seasons, increase thee, the years, the seers, what things are true; shine thou with the heavenly bright space (rocaná); illuminate (ā-bhā) all the four directions.
