Mangal dosha is a commonly found dosha. This dosha is also called Kuja dosha or Bhauma dosha. This dosha occurs when the placement of Mars in the horoscope is in certain houses that cause malefic influences. People, in whose natal chart Mars is placed inauspiciously, are called Mangliks.
Mangal dosha occurs when Mars is placed in the - ascendant, the second, fourth, seventh,
eighth or twelfth house of the horoscope. To ascertain this dosha, some of the ancient Rishis (learned men) of India also checked the Chandra Kundli or the Lunar horoscope.
People of both sexes can be Manglik. If a boy having Mangal dosha is married to a girl having Mangal dosha then the malefic affects are nullified leading to prosperity and a happy married life.
The most famous myth about being a Manglik is that if he/she is married to a non-Manglik then the spouse is bound to die. This does not happen to everybody. Such predicament is only true for horoscopes, which have a severely afflicted Mars. A good astrologer can do this determination. Approximately 42% of the population are supposed to be of Mangliks.
This dosha or fault has varying degrees. Some people can be strong Mangliks and some maybe mild. The milder dosha can be treated by prayers or chanting under the supervision of a Priest or an astrologer. It is not always necessary that the milder Mangliks have to get married to a manglik. They can easily lead a good life with non-Mangliks too.
If a marriage is solemnized without consulting the natal charts for the presence of manglik dosha, it can lead to a lot of troubles. Suppose either or the spouse is a manglik, then the married couple is likely to suffer from various problems like unnecessary arguments and undue emotional distress without being able to pin point the cause of the same. In many of the cases the marriage tends to lead to a divorce. To prevent things from going to such an extreme, the ancient sages of India recommended that the horoscopes of both the girl and boy be matched before marriage. If the horoscopes are found compatible then only one should go ahead with the marriage. Like always prevention is better than the cure.
