Rig Veda
स॒मा॒न्या वियु॑ते दू॒रेअ॑न्ते ध्रु॒वे प॒दे त॑स्थतुर्जाग॒रूके॑ । उ॒त स्वसा॑रा युव॒ती भव॑न्ती॒ आदु॑ ब्रुवाते मिथु॒नानि॒ नाम॑ ॥ समान्या वियुते दूरेअन्ते ध्रुवे पदे तस्थतुर्जागरूके । उत स्वसारा युवती भवन्ती आदु ब्रुवाते मिथुनानि नाम ॥
Common (in function), disjoined, of distant termination, they remain vigilant in a permanent station; being, as it were, sisters, and ever young; they therefore address each other by twin appellations.
