The planets Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn and the two shadow planets Rahu and Ketu constitute the Navgrahas. The nine " Grahas " or planets in our horoscope controls our Destiny, our Karmas and their outcomes. Each of these nine planets exerts a profound influence on our lives depending upon their placement & state in our horoscope as well as their transit.
A Navgrah Yantra is a combined Yantra to pacify all the nine planets. This Yantra is divided into nine squares, each one with a talisman representing one planet. It is an extremely useful & beneficial Yantra, since it's worship strengthens benefic planets & increases their positive influence and on the other hand, it also pacifies malefic planets & neutralizes their negative effects. This Yantra is recommended for all, particularly those in whose horoscope, more than 3 or 4 planets are malefic and therefore it is not possible or very difficult to pacify them individually. This Yantra should be worshipped life-long to ensure that you always get maximum advantage from your planets.
