Bhagavad Gita 10.29
अनन्तश्चास्मि नागानां वरुणो यादसामहम्।पितृ़णामर्यमा चास्मि यमः संयमतामहम्॥
anantaścāsmi nāgānāṃ varuṇo yādasāmaham |pitṛṇāmaryamā cāsmi yamaḥ saṃyamatāmaham ||
I am Ananta among the Nagas; I am Varuna among water-deities; Aryaman among the Manes; I am Yama among the governors.
I am the king-python among snakes, I am the aqueous principle among those that live in water, I am the father of fathers, and among rulers I am death.
Our plain-language meaning of this verse is waiting for scholar review.
