Rig Veda
प्र पर्व॑तानामुश॒ती उ॒पस्था॒दश्वे॑ इव॒ विषि॑ते॒ हास॑माने । गावे॑व शु॒भ्रे मा॒तरा॑ रिहा॒णे विपा॑ट् छुतु॒द्री पय॑सा जवेते ॥ प्र पर्वतानामुशती उपस्थादश्वे इव विषिते हासमाने । गावेव शुभ्रे मातरा रिहाणे विपाट् छुतुद्री पयसा जवेते ॥
Rushing from the flanks of the mountains, eager (to reach the sea) like two mares with loosened reins contending (with each other in speed), like two fair mother cows (hastening) to caress (their calves), the Vipās' and Śutudri, flow readily with (united) waters.
