If the planet Mars is placed in the 12th house, 1st house, 4th house, 7th house or 8th house from Lagna or Ascendant, then it forms Mangal Dosha in ones Birth Chart. If Mars occupies above houses in ones natal chart, then it will be considered as High manglik Dosha.
How do I know if I am Manglik or non Manglik?
Mangal dosha or kuja dosha or chovva dosham is the combination in the birth chart or horoscope where Mars (also known as Mangal or Kuja) is placed in the 2nd, 4th, 7th, 8th or 12th house in the Ascendant. A person with mangal dosh in his natal chart is called Manglik.
What happens if a Manglik marries a non Manglik?
If a chart promises good longetivity, even if a manglik marries a non-Manglik, no harm is caused. Next, bed relations and promise of child birth should be analysed. Children act as catalyst for most marriages to survive. An astrologer should also judge the financial aspects and advice accordingly.
