VIPAREETA RATNA (OPPOSITE GEMSTONE)
Vipareeta means opposite or gemstones used for weakening the effects of some planets in certain houses. If any house is occupied by an enemy of its Karaka, then the significations of the house suffer. Keeping this principle in view, the first house to be checked in any chart is the ninth house of fortune and Dharma with Jupiter & Sun as the significator. Rahu and Saturn are the enemies of these significator and if they are placed in the ninth house, they shall damage fortune and Dharma. The remedy is to strengthen the concerned Karaka by wearing its gemstone in the ring finger. Suka Nadi states that if Rahu is in the ninth house, then the native has good fortune after wearing a Topaz. The same principle of Vipareeta Ratna (Opposite Gemstone) has been used here. Rahu is the enemy of Jupiter and since it is placed in the ninth house, the use of a Topaz (gemstone of Jupiter) removes the misfortune caused by Rahu. Similarly, if Saturn is in the ninth house, then the person may suffer from poverty/ failure in the homeland after 36 years. To remove this evil, a ruby, the gemstone of the Sun (Saturn’s enemy) is worn.
GEMSTONES VS. DASAS
Hands in which the gemstones are worn to be chosen on the basis of certain criteria. The right hand is ruled Jupiter and the left hand by Venus indicating increase (right hand) or decrease (lift hand) of life force.
Thus, if gemstones have to be prescribed to decrease the evil effects of a malefic planet, its gemstone should be used in the left hand. Such use should be temporary covering the dasa-bhukti of the planet.
When the planet is a malefic for the horoscope, the maleficence of the planet can be reduced by wearing a counter gemstone temporarily during the Dasa-bhukti of the planet. If instead a gem is to be worn for the main Dasa planet itself, then it should be worn in the left hand. For example, if Rahu is malefic then during its period a Yellow Sapphire/Topaz/Citrine can be worn in the right hand ring finger or Hessonite/Brown Tourmaline etc can be worn in the left hand middle finger.
