Text 39

वायुर्यमोऽग्निर्वरुणः शशाङ्कः
प्रजापतिस्त्वं प्रपितामहश्च ।
नमो नमस्तेऽस्तु सहस्रकृत्वः
पुनश्च भूयोऽपि नमो नमस्ते ॥३९॥

vāyur yamo 'gnir varuṇaḥ śaśāńkaḥ
prajāpatis tvaḿ prapitāmahaś ca
namo namas te 'stu sahasra-kṛtvaḥ
punaś ca bhūyo 'pi namo namas te

Translation:

You are air, and You are the supreme controller! You are fire, You are water, and You are the moon! You are Brahma, the first living creature, and You are the great-grandfather. I therefore offer my respectful obeisances unto You a thousand times, and again and yet again!

Purport:

The Lord is addressed here as air because the air is the most important representation of all the demigods, being all-pervasive. Arjuna also addresses Krishna as the great-grandfather because He is the father of Brahma, the first living creature in the universe.
