Mangal Dosha, also called Manglik Dosha, is a traditional concept in Vedic astrology associated with particular placements of Mars in a birth chart. Some astrologers consider it when interpreting marriage compatibility and relationship concerns.
However, Mangal Dosha should not automatically be treated as the cause of delayed marriage, marital difficulties or an unsuccessful relationship. Its interpretation varies across astrological traditions and depends on the wider chart and the method being used.
Do not make marriage decisions out of fear of a single astrological placement. Any assessment should explain the reasoning, acknowledge uncertainty and avoid presenting an astrological interpretation as an inevitable outcome.
