Mangal Dosha (also called Kuja Dosha or Manglik Dosha) is an astrological condition in Vedic astrology that occurs when Mars (Mangal) is placed in certain houses of the birth chart.

According to traditional beliefs, this placement can affect marriage and relationships. However, many factors in a horoscope can modify or cancel this dosha, including:

• Mars in its own sign (Aries or Scorpio)
• Mars aspected by benefic planets (Jupiter, Venus)
• Both partners being Manglik (doshas cancel out)
• Certain exceptions based on the specific house and sign

Note: This is a simplified analysis. For accurate results, consult a qualified Vedic astrologer with your complete birth chart.
