Because eclipses happen near it, the myths call it a head without a body. Tradition reads Rahu as hunger and restlessness: a drive toward whatever is new, foreign or out of reach. It always moves backward through the zodiac.

In the dasha cycle

In the Vimshottari order, Rahu is followed by Jupiter. The period of Rahu lasts 18 years when it runs in full. Read more about the system on the dasha page.
