Mangal Dosha, also known as Kuja Dosha or Mangalik Dosha, is a condition in Vedic astrology where the placement of the planet Mars in certain houses of an individual’s birth chart (kundali) is believed to exert a malefic influence. The specific houses associated with Manglik Dosha are the first, fourth, seventh, eighth, and twelfth. According to astrological traditions, the presence of Mars in these houses can lead to challenges in one’s marital life.
