Myth: Mangal dosha ruins marriages

Mangal dosha is usually defined as Mars in the 1st, 2nd, 4th, 7th, 8th or 12th house. That's six houses out of twelve, so by the simplest rule about half of everyone has it.

Classical texts also list many conditions that cancel it, and traditional matching looks at it in both charts together, never one alone.

Mars placed there says something real: about temperament, about how you handle conflict at home. It isn't a verdict on whether a marriage will work, and nobody should be turned down over it.
