Rig Veda
ऋ॒तं चि॑कित्व ऋ॒तमिच्चि॑किद्ध्यृ॒तस्य॒ धारा॒ अनु॑ तृन्धि पू॒र्वीः । नाहं या॒तुं सह॑सा॒ न द्व॒येन॑ ऋ॒तं स॑पाम्यरु॒षस्य॒ वृष्ण॑: ॥ ऋतं चिकित्व ऋतमिच्चिकिद्ध्यृतस्य धारा अनु तृन्धि पूर्वीः । नाहं यातुं सहसा न द्वयेन ऋतं सपाम्यरुषस्य वृष्णः ॥
Agni, who know (the purpose of) the sacrifice, assent to this rite; be favourable to the copious showers of water; (endowed) with strength, (I undertake) not (to obstruct) sacred acts, nor adjure the rite with both (truth and untruth), but (repeate the praise) of the resplendent showerer (of benefits).
