Rahu is said to be the snake head without the body, and the Sun and Moon exit from his throat when he tries to swallow them. This cycle creates the grahana, an eclipse of the Sun and the Moon, which represents Rahu's temporary revenge. Rahu is also said to cause eclipses on the luminaries themselves.
