Ashtakuta (Gun Milan) - 36 Point Matching
Ashtakoota Gun Milan scores two charts out of 36 across eight kootas, and the weights are fixed: Varna 1 point, Vashya 2, Tara 3, Yoni 4, Graha Maitri 5, Gana 6, Bhakoot 7 and Nadi 8.
Every one of them is computed from just two quantities per person, the Moon's nakshatra and the Moon's sign, which is why the method needs an accurate Moon rather than a full chart. This page computes all eight and shows the score and the reason for each.
The bands this app applies to the total are 32 and above Excellent, 27 to 31 Very Good, 21 to 26 Good, 18 to 20 Average, 14 to 17 Below Average, and below 14 Not Recommended. Those bands are the app's presentation of a widely used convention, not a verse in a text, and they are stated here so the number is not mistaken for a verdict the classics deliver.
Nadi carries 8 of the 36 and is scored on the Aadi, Madhya and Antya classification of the birth nakshatra. Different nadis score the full 8.
The same nadi is Eka-Nadi dosha, but the classical pariharas nullify it in three cases: the same nakshatra with different rashis, the same rashi with different nakshatras, and a shared birth star that belongs to the exempt set. Where none of those applies and the couple share both the star and the rashi, the score stands at 0, which is the severest attested form.
Bhakoot carries 7 and is scored on the distance between the two Moon signs. The 2 and 12, 5 and 9, and 6 and 8 relationships are the inauspicious ones. Two pariharas restore the full 7: the unanimously attested one, where both Moon signs share a single lord, as Aries and Scorpio both do under Mars, and a weaker one, where the two sign lords are mutual natural friends.
The engine restores the points in both cases and says which parihara applied, since the sources do not supply a partial figure and inventing one would be an interpolation.
The Dashakoota toggle switches the koota table to the Tamil ten-porutham system, which reads the same birth star and Moon sign through a different set of tests. Each porutham is scored favourable, partial or unfavourable, worth 1, 0.5 or 0, for a maximum of 10. The page reports the count of fully favourable poruthams alongside the point total, because the two are not the same measure.
Rajju and Vedha are the two the tradition treats as critical. Rajju maps each nakshatra onto a part of the body through a nine-step cycle running Pada, Kati, Nabhi, Kantha and Siro and back down again, and a shared rajju is a serious dosha. Vedha pairs nakshatras that afflict each other; Chitra is unpaired and has no Vedha partner. Both are flagged separately from the total rather than buried in it.
Papasamyam is the Kerala practice of balancing the malefic load the two charts carry, and it is grounded in Prasna Marga chapter XXI. The papa grahas are the Sun, Mars, Saturn, Rahu and Ketu, and the papa houses are the 1st, 2nd, 4th, 7th, 8th and 12th.
Those houses are counted from three reference points with different weights: the ascendant at 1.0, the Moon at 0.5 and Venus at 0.25. The alliance is sanctioned when the bride's weighted total is equal to or less than the groom's.
Manglik status is computed for each chart separately using the same three reference points, and the exceptions that nullify the dosha are applied before the status is reported. Papasamyam and Manglik are not duplicates of each other: Manglik asks whether one planet sits in one of a set of houses, while Papasamyam sums all five malefics across three references and then compares the two people. A couple can pass one and fail the other.
Beyond the kootas, the page computes three chart-level comparisons from the two natal charts. Graha Maitri here is the compound natural friendship of the two Moon-sign lords, merged by the classical rule where friend with enemy resolves to neutral. The navamsa comparison reads each Moon's D9 sign and the relation between them. The marriage significators, the seventh lord and Venus in each chart, are reported alongside.
Bhrigu Bindu, the midpoint of Rahu and the Moon, is shown as a position only and deliberately carries no compatibility judgement. The reason is on the card: a search across BPHS volumes 1 and 2, Jaimini's Upadesha Sutras, Uttara Kalamrita and Prasna Marga returned no locus for it.
The construction is real and is computed exactly; what is missing is any classical text that says what it means for a couple, so the app prints the point and stops rather than asserting a marriage verdict in its own voice.
