Bhagavad Gita 9.17

पिताऽहमस्य जगतो माता धाता पितामहः।वेद्यं पवित्रमोंकार ऋक् साम यजुरेव च॥

pitā'hamasya jagato mātā dhātā pitāmahaḥ |vedyaṃ pavitramoṃkāra ṛk sāma yajureva ca ||

I am the father of this world, the mother, the dispenser of the fruits of actions, and the grandfather; the one thing to be known, the purifier, the sacred monosyllable (Om), and also the Rik, Sama, and Yajur Vedas.

I am the Father of the universe, its Mother, Nourisher, and Grandfather; I am the Knowable and the Pure; I am Om, and I am the Sacred Scriptures.
