Rule 5 cancels 15 points when Jupiter occupies the same sign as Mars, a combination classically called Guru-Mangal yoga. Jupiter’s presence is read as channelling Martian energy toward principled action rather than raw conflict.
This page covers how rule 5 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 5 evaluated?
Our engine defines conjunction as same-sign occupancy, with no degree orb. Mars at 2° Leo and Jupiter at 28° Leo count as conjunct, even though they sit 26 degrees apart.
This is a deliberate choice and worth stating plainly, because it is a place where implementations reasonably differ. Whole-sign conjunction is consistent with the whole-sign house system used throughout the method. A degree-orb implementation — commonly 8° or 10° — would find this rule applying less often and would produce different results on a meaningful number of charts.
Why does conjunction score less than aspect?
Rule 4 scores 20 and rule 5 scores 15, which can seem backwards since conjunction looks like the closer relationship. The weighting follows citation frequency in the classical material: benefic aspect is the more widely and consistently named neutraliser.
Can rules 4 and 5 both apply?
Not to the same Jupiter. Jupiter cannot simultaneously occupy Mars’s sign and aspect it from the 5th, 7th or 9th. The two rules are mutually exclusive in practice, though our engine evaluates them independently rather than assuming so.
What does rule 5 do to a real score?
Mars and Jupiter both in Leo, with Leo as the 8th house from a Capricorn Ascendant.
The 8th house base weight of 90 with an Ascendant trigger gives a raw 50.0. Rule 5 removes 15%, leaving a net 43 out of 100 — the Mild band.
Because rule 5 is never absorbed, it combines with dignity rules. Mars in Scorpio with Jupiter also in Scorpio scores 25 plus 15, for 40% cancellation.
What should you know before relying on this rule?
This rule is never absorbed, and it stacks with every other rule up to the 85% cap.
One caution about the name: Guru-Mangal yoga is discussed in classical literature well beyond the Dosha Bhanga context, where it carries its own significations for temperament and profession. Those broader readings are not what rule 5 scores. Here it does one job — reducing the dosha figure by 15.
How does rule 5 compare with the other nine?
Rule 5 carries 15 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 4 — Jupiter aspect — read the rule
- Rule 6 — Chandra-Mangal — read the rule
- Rule 1 — own sign — read the rule
The complete ten-rule reference sets all of them out together with their weights and sources.
Frequently asked questions
What is Guru-Mangal yoga? Jupiter and Mars occupying the same sign. In the cancellation context it is worth 15 points.
Is a degree orb used for conjunction? No. Same-sign occupancy is the test, consistent with the whole-sign house system used throughout.
Why does conjunction score less than aspect? Because benefic aspect is the more frequently and consistently cited neutraliser in the classical material.
Can Jupiter both aspect and be conjunct Mars? No — the two positions are mutually exclusive for a single Jupiter.
Does Guru-Mangal yoga have other meanings? Yes, well beyond Mangal Dosha. Those broader significations are separate from what this rule scores.
Is this rule ever absorbed by rule 8? No. Only rules 1, 2, 3 and 7 are absorbed, because only those restate Mars’s own placement.
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.
