Mangal Dosha in the Birth Chart and the Navamsa
Mars can be Manglik from the rising sign and quiet in the Navamsa, or the reverse. Matchers who use both are running two house tests.
Two lagnas, one Mars
Mangal dosha in the lagna chart is Mars in the 1st, 2nd, 4th, 7th, 8th, or 12th counted from the birth ascendant. Mangal dosha in the Navamsa is the same list counted from the D9 lagna, which is often a different sign. Mars has one longitude. The house number changes because the starting sign changes. A planet in the 10th from the birth lagna can sit in the 7th from the Navamsa lagna.
The Moon-chart version is a third count, from the Moon's sign, and it is not the Navamsa. Keep the three references apart.
Which result is heavier
Mars Manglik in the birth chart and not in the D9 is the lighter marriage case. The public life shows the dosha, and the spouse varga does not. Mars Manglik in both is the heavier case, because the varga used for the partner repeats the heat. Mars clear in the birth chart and Manglik only in the D9 is easy to miss if you never open the Navamsa, and it still belongs in a careful match.
Dignity travels with Mars into both charts. Exaltation in Capricorn, or own sign Aries or Scorpio, softens whichever chart contains it. A fallen Mars in Cancer is harsher in whichever chart places Cancer in a Kuja house.
The 7th lord is still outside this test
Neither Mangal count inspects Venus, or Jupiter in a woman's chart, or the condition of the 7th lord. A double Manglik Mars with a strong 7th lord and a sound Venus is a heated match with support. A Mars that is clear in both D1 and D9, beside a 7th lord in the 8th, is a quiet Mangal screen and a difficult marriage house.
Use the birth chart as the life, the Navamsa as the spouse test, and the dasha of Mars, 7 years, as the period when a Manglik Mars is personally loud.
Frequently asked questions
Does D9 Mangal replace D1 Mangal?
No. The birth chart counts from the rising sign. The Navamsa counts from the D9 lagna. Both can be true.
Is the Moon chart the same as the Navamsa?
No. The Moon chart turns the Moon's sign into the 1st. The Navamsa is the ninefold divisional chart.
Which combination is heavier?
Mars in a Kuja house in both the birth chart and the Navamsa. One chart alone is the lighter case.
