Verse 9.17

पिताऽहमस्य जगतो माता धाता पितामहः। वेद्यं पवित्रमोंकार ऋक् साम यजुरेव च।।9.17।।

pitāham asya jagato mātā dhātā pitāmahaḥ vedyaṁ pavitram oṁkāra ṛik sāma yajur eva cha

Meaning

I'm the ultimate father, mother, and even grandpa of this world, the one who decides what you get for your actions. I'm the only one you need to know, the big purifier, the sacred 'Om', and also the Rik, Sama, and Yajur Vedas.

Commentary

OMG, so like, Krishna is totally the ultimate dad, mom, and grandpa of this whole universe, the one who gives you the rewards for all your actions. He's the only one you *need* to know, the ultimate purifier, the sacred 'Om', and also the whole deal with the Rik, Sama, and Yajur Vedas. It's like, the big boss of everything. The pure Satchidananda Para Brahman (Existence-Knowledge-Bliss Absolute) is the ultimate grandpa. The 'one thing to be known'? That's the Supreme Being. Purifier? Think of it like a holy bath in the Ganges, or chanting the Gayatri mantra—it cleanses your soul, inside and out. And yeah, that includes the Atharva Veda too.
