Kuja Dosham

"Dhana vyayecha pathale jamitre chashtame kujaha;
Strinam bharthru vinasamcha bharthunam strivinasanam".
This means: - "If Kuja is in the 2nd, 12th, 4th, 7th and 8th houses in the horoscope of the female, the death of the husband will occur; similar situation in the husband's horoscope causes the death of wife." Kuja (Mangal) placed in the 1st, 2nd, 4th, 7th, 8th and 12th house from ascendant (Lagna), Chandra and Sukra results in the Mangalika Dosha.
