Varuna and Uranus
Georges Dumézil made a cautious case for the identity of Varuna and the Greek god Uranus at the earliest Indo-European cultural level. Dumézil's identification of mythic elements shared by the two figures, relying on both linguistic interpretation and common attributes, myths, and relationships to other deities, was taken up by Robert Graves and others. The identification of the name Ouranos with the Hindu Varuna, based in part on a posited PIE root *-ŭer with a sense of "binding"— ancient king god Varuna binds the wicked, ancient king god Uranus binds the Cyclopes— is widely rejected by those who find the most probable etymology is from Proto-Greek *worsanos, from a PIE root *wers- "to moisten, to drip" (referring to the rain). Other theories identify Varuna with the Greek God Poseidon or Roman Neptune of the seas.
Uranus is associated with the night sky as his name literally means "Sky", and Varuna is a god of the sky and the celestial ocean which is the milky way or Kshira (क्षीर, milk) sagar. Laksmi is said to have arisen from the ocean of milk and therefore be the daughter of Varuna. Aphrodite is said to have been born from the falling of the testicles of Uranus in the ocean after his castration. Both Laksmi and Aphrodite are associated with the planet Venus. This shared nature of the two deities also leads to their identity being linked together.
