Tortoise is one of the four celestial animals as per Chinese Fengshui and is of great significance in both Vastu as well as Fengshui. Tortoise has a very long life span and therefore it is considered very auspicious and hence it is recommended that a tortoise should be kept at house so that the family members may have a long life. A Tortoise made from mixed metals also works as a remedial measure for correction of Vastu faults since it has great power to balance the environmental energy around us as well as removal of negative energy thereby purifying the place where it is kept. This Tortoise can also help in studies if the same is kept on or near your study table. Similarly it can be kept on the office table as well. Navgrah Tortoise should be kept in the North direction of the house.
The term Navgraha denotes the nine celestial bodies which are central to astrological calculations (and beliefs & not the nine planets as it is frequently erroneously translated). The 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 karma, our desires and their outcomes. Each of these nine planets exerts an influence in our lives, which is called "Dasha" and it can be known from one's horoscope. Hence Navgrah Tortoise should be kept to reduce the negative effects and improve the positive energies of planets.
