राहु शांति पूजा
Rahu is a Navagraha, one of the nine dominant planets, which can strongly influence people and their lives. Astrologically, Rahu is counted as a planet but is indeed regarded as the head of a mythological snake, whose tail is Ketu, his planetary counterpart. Rahu is unique in many respects. Unlike other planets, he doesn’t have a physical existence and remains only as the Northern lunar node, the Northern point of intersection of the orbits of the Sun and the Moon. So Rahu is considered as a ChayaGraha, the shadow planet. His color is said to be black.
As he doesn’t exist in space, Rahu doesn’t own any sign in the natural zodiac but acts only as an agent of the owner-planet of the sign, in which he is placed in a natal chart. Rahu also takes about 1 ½ years to travel through a sign and is said to be somewhat similar to planet Saturn in some respects.
