What are the cancellation rules for Manglik Dosha?

Vedic astrology recognises several cancellation rules (Manglik Dosha Parihara) that neutralise or reduce the dosha: (1) Both partners are Manglik — the doshas cancel each other, (2) Mars is placed in its own sign (Aries or Scorpio) or in exaltation (Capricorn), (3) Mars is aspected by a benefic planet such as Jupiter or Venus, (4) The 7th or 8th house has a strong benefic influence, (5) The native is born under certain specific tithis where Manglik effects are weakened. A detailed kundali matching analysis can identify which cancellations apply to your chart. A strong match with applicable cancellations is often safer than a non-Manglik-to-non-Manglik match with other chart weaknesses.
