Mangala Dosha

Mangala dosha is a rule about the position of Mars in the birth chart that tradition ties to the theme of marriage. It answers two questions: has Mars fallen into one of the houses tradition holds to be awkward for married life, and do other conditions of the chart lift that position. The dosha names a factor that asks for attention, not a sentence upon a marriage, and it does not enter the thirty-six gunas of Ashta Kuta — it is reckoned separately. The reference point, meanwhile, is not single: Mars's position is reckoned from the Lagna, from the Moon and from Venus. The cancellations run the same way: a conjunction of Mars with Jupiter or with the Moon, and Jupiter or Venus in the Lagna, counteract the dosha; Parashara cancels it otherwise — his rule fires when both partners carry it.

Place in the system

The dosha is determined by house position: a reference point is taken, the houses are counted from it, and one looks at whether Mars has fallen into one of "those" houses.

A dosha and a planet are different things. Mars is in every chart: it is one of the nine grahas, and it describes will, drive and the way one acts in a clash. The dosha arises only at a particular position of Mars and only in relation to the question of marriage. The house decides, however strong or weak Mars may be. The dosha's second name is Kuja dosha; kuja and mangala are two Sanskrit names of the same planet.

The set of houses differs by school, and the spread is wider than is usually supposed. The classical list is the twelfth, fourth, seventh and eighth from the Lagna. Two printed formulas give a full list, and each gives five houses: one adds the second to those four, the other adds the first. This reckoning follows the former. The same page introduces three reference points at once — the Lagna, the Moon and Venus — explaining that the Lagna answers for the body, the Moon for the mind and Venus for marital closeness, and it grades the weight: from the Lagna the dosha is weaker, from the Moon stronger, from Venus strongest of all. The six houses used by many calculators are the union of both formulas, and no single one prints such a set.

Hence a consequence worth knowing: two reckonings may disagree on whether the dosha is present at all, and both will be made in good faith.

Practical meaning

Behind the rule lies a simple thought: Mars is the planet of drive and collision, and in the houses tied to home, family and shared life tradition finds that drive uncomfortable. The dosha names a position that calls for attention, not a doomed marriage.

Cancellations are part of the rule itself: the text that introduces the dosha goes on at once to list the conditions under which it does not operate. There are three: Mars sharing a sign with Jupiter, Mars sharing a sign with the Moon, and Jupiter or Venus in the Lagna. Separately the dosha is set aside when both partners carry it — that is Parashara's rule. And there are conditions under which it never arises at all: each of the five houses has its own exempt signs, and in Leo and Aquarius Mars gives no dosha in any house.

The rule that "the dosha passes after twenty-eight years" has no printed source. It circulates in practice but occurs in none of the texts that were checked.

In daily practice

In the reckoning the dosha is shown apart from the sum of the kutas and is not added to them. Three things are printed: whether it is present, whether it is cancelled, and by which reference point it was triggered.

When the birth time is unknown the Lagna is undetermined, and the dosha is reckoned from the Moon and Venus only. The result in that case remains incomplete, and the reckoning says so.

If both partners have the dosha, the reckoning calls it mutual neutralisation. If only one does, it says the dosha is one-sided, and no more than that: it remains one factor among others, not a final conclusion about the couple.
