Rule 1 cancels 25 points when Mars occupies Aries or Scorpio, its two own signs. A planet in its own sign is classically read as strong and self-contained, and the Dosha Bhanga tradition holds that Mars so placed does not inflict the dosha at full force.
This page covers how rule 1 is evaluated, what it is worth, the cases where it interacts with other rules, and a worked example with the actual arithmetic.
How is rule 1 evaluated?
The rule is chart-general: it applies wherever Mars sits, from any reference point, and does not depend on which house Mars occupies. Only the sign matters.
Aries and Scorpio score identically at 25. Classical practice distinguishes them in expression — Aries acts outward and immediately, Scorpio sustains pressure inwardly — but the cancellation weight does not separate them. Nor does our scoring separate the Moolatrikona portion of Aries (0°–12°), which classical texts rank above ordinary own-sign dignity.
Is exaltation stronger than own sign here?
Not in this scoring. Rule 2 (Mars exalted in Capricorn) also weighs 25. Classical practice generally ranks exaltation above own sign in strength, but the cancellation rules treat them as equivalent, and we have not invented a distinction the sources do not draw.
Does the Moolatrikona range change the score?
No. Mars at 5° Aries and Mars at 25° Aries both score 25 under this rule. The Moolatrikona distinction is real in classical strength assessment but is not part of the Dosha Bhanga weighting.
What does rule 1 do to a real score?
Mars in Scorpio in the 8th house from the Ascendant, with no other rule applying.
The 8th house carries a base weight of 90, and an Ascendant trigger contributes 50% of it, giving a raw figure of 50.0. Rule 1 removes 25%, leaving a net 38 out of 100 — the Mild band.
Note what the rule does not do. It does not remove the dosha; the status stays Manglik or Anshik depending on how many reference points trigger. It reduces severity, which is a different measurement.
What should you know before relying on this rule?
This rule is absorbed when rule 8 applies. Mars in Aries in the 1st house and Mars in Scorpio in the 4th house are both named sign-and-house exceptions. In those two cases the exception scores 35 and rule 1 scores nothing, because the exception already describes the dignity that rule 1 would score. Counting both to reach 60 credits one classical fact twice.
Your report will show rule 1 as present but already counted in those cases, never as absent.
How does rule 1 compare with the other nine?
Rule 1 carries 25 of the 100 points available across the ten rules, and cancellation is capped at 85% in total — classical tradition treats a dosha as mitigated rather than erased, so no chart reaches zero.
The rules most worth reading alongside this one:
- Rule 2 — exalted — read the rule
- Rule 8 — exceptions — read the rule
- Rule 10 — navamsa — read the rule
The complete ten-rule reference sets all of them out together with their weights and sources.
Frequently asked questions
Does Mars in Aries always cancel Mangal Dosha? It always contributes 25 points of cancellation, which is not the same as removing the dosha. Cancellation is capped at 85% overall and never reaches 100%.
Is Aries or Scorpio better? They score identically. The difference is in how Mars expresses, not in cancellation weight.
Does this rule apply from the Moon and Venus too? Yes. Rule 1 depends only on the sign Mars occupies, so it applies regardless of which reference point triggered the dosha.
Why is my score still high with Mars in its own sign? Because 25 points of cancellation against a high raw figure still leaves a substantial net. Mars in Scorpio in the 8th from all three reference points gives a raw 100, and 25% cancellation leaves 75.
What if Mars is in Aries in the 1st house? Then rule 8 applies instead at 35 points, and rule 1 is absorbed into it rather than added.
Is Moolatrikona counted separately? No. Our scoring treats the whole sign uniformly at 25.
Where to go next
To see which of the ten rules actually fire on your chart rather than reading them in the abstract, run the cancellation calculator — it reports every rule tested, including those that did not apply and those that could not be evaluated. Our methodology documents how the weights are derived and where our scoring decisions depart from classical instruction.
