I have been asked to clarify many misconceptions about ‘Kuja Dosha’ or ‘Manglik’ in a horoscope. Kuja, Angaraka and Mangala are some of the names for Mars and Mars effect being posited in certain houses of horoscope causes Kuja / Angaraka / Mangala Dosha. All over India, astrologers check this Dosha while matching horoscopes for marriage purposes. Especially in North India, they give lot of importance for ‘Manglik’ and many girls remain unmarried for not getting a suitable match.
Mars is ranked as a malefic and being of Martian nature is associated with aggression and thereby can cause some destruction to the house he is posited in. While this is generally true, it cannot be accepted as bad across the board since Mars can be Yogakaraka for certain Lagnas and therefore it is unwise to assume that he will do harm to all people.
The Classical texts state the following regarding Kuja Dosha.
Mars posited in 1, 2, 4, 5, 7, 8 & 12 reckoned from Lagna causes Kuja Dosha
They also state that these positions be examined reckoned from Moon and Venus.
Intensity of Dosha when reckoned from Moon and Venus are equal
Intensity of Dosha when reckoned from Lagna is twice that from Moon and Venus.
For Males, Mars in 2, 7 & 8 and for Females Mars in 4, 8 & 12, the Dosha is maximum
Dosha for the boy should be greater than the girl.
For Cancer and Leo Lagna, Mars is Yogakaraka and hence there is no Kuja Dosha.
For Gemini and Virgo Lagna it is 100% Dosha
For Taurus and Libra Lagna it is 100% Dosha
For Sagittarius and Pisces Lagna it is 50% Dosha
For Capricorn and Aquarius Lagna it is 75% Dosha
For Aries and Scorpio Lagna it is 25% Dosha
While assessing the strength of Kuja Dosha we have to see the strength of Mars. For this we see the Shadbala strength and specially Sthana Bala which is important. Generally all planets when they are exalted they are powerful and give full effect. When in Mulatrikona give 75% effect, Own House 50% effect, Friendly House 25% effect and in Adhi Mitra house (Natural friend + temporary friend) give 3/8 effect.
Note: If we count Mars position from Lagna, Moon and also Venus, then the whole world population will have Kuja Dosha and therefore I recommend that we stick to Lagna only.Manglik Dosha | Kuja Dosha Effects and Remedies
