As discussed in Astrology, there are 9 planets, placement of which causes the destiny of a person to change during the lifetime. Out of these 9 planets, 7 of these planets (Saturn, Venus, Jupiter, Mercury, Mars, Moon & Sun) symbolize the 7 colors of the rainbow, while the balance 2 planets (Rahu & Ketu) symbolize those radiations which are not visible to the naked eye. Rainbow colors can be seen through a prism in the form of Cosmic rays, the same can be seen on our earth in condensed form as Natural Gem Stones. Thus, we can reverse the ill-effects of the planets, to some extent, by using the divine nature of these Gem Stones.
