Carl Jung tells us that “Sometimes the Kore and mother-figures slithers down altogether to the animal kingdom. When this occurs we may see her represented as the snake, the crocodile, or other salamander-like, saurian creatures.” 
In the above image we see two Nagas. It looks as if one is male and one female. Males are called Nagas and the females are called Nagis or Nagini. Naga means snake. The Nagas are Hindu mythical creatures that take the form of the snake. The Nagas are half human and half snake. Myth has it that they can change at will. It is said that the “Nagas were the sons of earth.”  They had “plenty of wealth”, beautiful women, and magnificent cities [ibid].
In the Bhagavata Purana, the nether world is divided into seven regions. The lowest region is Nagaloka, the realm if the Nagas. It is ruled by Vasuki. It is said that Shiva wears Vasuki round his neck as an ornament. Shiva is sometimes called Naga Natha.
