पिताहमस्य जगतो माता धाता पितामहः। वेद्यं पवित्रमोंकार ऋक्साम यजुरेव च ॥
pitāhamasya jagato mātā dhātā pitāmahaḥ | vedyaṃ pavitramoṃkāra ṛksāma yajureva ca ||

I am the father of this world, the mother, the sustainer and the grandsire. I am what is to be known, the purifier, the syllable Om, and the Rig, Sama and Yajur Vedas.
