Sheshnaga: The King Of All Serpents

Shesha Naga is believed to be the one who is accountable for the notion of the gravitational force and makes sure that all planets and stars orbit around each other.
Sheshnaga is said to hold all the planets of the universe on his hoods and to constantly sing the glories of Vishnu from all his mouths.
Lord Vishnu is usually portrayed as resting on Shesha Naga.
