I am Ananta among the serpents; Varuṇa among the aquatics; Aryamā among the ancestors, and I am time among the subjugators.

Nāgānām — of celestial serpents — anantaḥ — Śeṣa, the infinite, couch of Viṣṇu. Yādasām — of aquatic beings — varuṇaḥ — god of waters.

Pitṝṇām — of the ancestors — aryamā — one of the twelve Ādityas, god of the manes. Saṃyamatām — of those who control/punish — yamaḥ — the god of death, who subjugates all.

The Lord is the death of death.
