Rig Veda
मा॒ता च॒ यत्र॑ दुहि॒ता च॑ धे॒नू स॑ब॒र्दुघे॑ धा॒पये॑ते समी॒ची । ऋ॒तस्य॒ ते सद॑सीळे अ॒न्तर्म॒हद्दे॒वाना॑मसुर॒त्वमेक॑म् ॥ माता च यत्र दुहिता च धेनू सबर्दुघे धापयेते समीची । ऋतस्य ते सदसीळे अन्तर्महद्देवानामसुरत्वमेकम् ॥
Where the mother and daughter, two productive kine, unite, they nourish each other; I worship them both in (the firmament), the dwelling of the waters great and unequalled is the might of the gods.
