Nagina

The Nagina is a snake in the form of a woman. In popular belief the snake is associated with wealth, fertility and power. In tantric symbolism, the snake represents the primal creative energy or Kundalini, which lies dormant in the space of the spine, which, when aroused, ascends and activates the chakras of the subtle body.
It is also the title of a movie made in Bombay. In the movie, the Nagina, played sumptuously by Sridevi, is discovered by her mother-in-law in her true form.
