The term Navagraha denotes the nine celestial bodies which are central to astrological calculations (and beliefs) (and not the nine planets as it is frequently erroneously translated). The sun, the moon, mars, mercury, jupiter, venus, saturn and the two shadow planets Rahu and Ketu constitute the Navagrahas. The nine "grahas" or planets in our horoscope control our karma, our desires and their outcomes. Each of these nine planets exerts an influence in our lives, which is called "dasa" and it can be known from one's horoscope. Navagraha Puja is undertaken to reduce the negative effects and improve the positive energies related to a person. Many a times we hear people say our time is running bad. These bad times are attributed to the different Grahas (Planets), and their position in the current time. These Grahas can be appeased by performing the Grah shanti Puja. There are 2 ways to perform this Puja. If you know which Graha is affecting you unfavorably, then tell us the name and we can perform the Puja for you. The other way is for us to find out from your Janma Patri and then perform the Puja for the particular Graha. specifically 7 1/2 years Saturn period.
