To make you better understand the subject, I would like to explain to you the basics about the other planets, before discussing about Lord Shani. The trinity Lords; i.e. Brahma, Vishnu and Mahesha are responsible for Generation, Operation and Destruction of the Universe. To deliver us the results of our own actions, God himself has been incarnated in the form of the planets. Our classics clearly declare that all of these nine planets are the icons of various incarnations of Lord Vishnu. So the Sun, the Moon, the Mars, the Mercury, the Jupiter, the Venus, the Shani, the Rahu and the Ketu are known to be the incarnations of Lord Rama, Krishna, Narsimha, Buddha, Vaman, Parashurama, Kurma, Varaha and Matsya respectively. There is another fact regarding Lord Shani, which needs to be clearly understood here over. It is that Lord Shani appeared as the son of Lord Sun, who himself is an incarnation of Idealistic Lord Rama. Apart from this, even all the occupants of divine land, do also come under the reign of the planets itself. This clarifies that the planets are even more powerful than Lord Indra or any other god. The jurisdiction of the planets is larger than that of the god's himself. Accordingly, it has been declared in the classics very clearly-
