The position of Rahu in 9th House for Virgo Ascendant and Ketu also changes according to the way Sun and Moonwalk on their respective paths in the universe. That is why, if the Moon is also at the point of Rahu (or Ketu) during the full moon, then the shadow of the Earth causes a lunar eclipse because the Moon and the Sun are in opposite directions at the time of the full moon.
