Limits of kundli milan
Kundli milan, the matching of two charts, has clear limits. A numerical score or a single rule cannot describe a relationship, and the traditional texts themselves describe several factors beyond the matching.
What it is
Matching compares the two people's birth data at one point, using the Moon's nakshatra and sign. It does not account for each person's full chart, dashas, character, health, or the relationship's history.
How it is worked out or read
The site does not produce a match score. A future tool would show each step of a matching method and its source, so the user can see what is included and what is not.
Where it appears on this site
The matching limits are summarised in the ashtakoota article. Speak to a qualified astrologer before deciding anything about a marriage.
What matching can and cannot show
Matching compares two charts at a single point each, usually the Moon's nakshatra and sign. It can show how the two people's birth details relate in the terms of the method, and it can name areas of ease or friction that the tradition describes. It cannot show the full character of either person, how the relationship will develop, or the choices the two will make together.
Recognising these limits is part of reading the method honestly. A total or a list of agreements is a tool for discussion, not a forecast, and its value depends on what it leaves out as much as on what it includes.
The gap between data and life
Two people with a favourable comparison may still have a difficult relationship, and two with a less favourable comparison may do well together. The difference lies in the people, their choices, their families and many factors that no chart records. Traditional teachers often say that the method is a starting point for conversation, and that the relationship itself is the thing to study.
A careful reader keeps this gap in view and describes the comparison as one input among many, rather than as an answer.
Responsible use
Anyone using a matching method should share the results with care and only with the people whose details are involved. The decision to marry belongs to the people concerned, and any practitioner they consult should be asked to explain the method, its sources and its limits. This site does not provide a match score and does not give verdicts on relationships.
Where the method is most often misused
Matching is most often misused when a single comparison is presented as a decision, when a practitioner's personal view is presented as the method, or when a low total is used to end a relationship without further conversation. A reader should watch for these habits and ask what the method has actually established.
Honest language about matching
Matching results are best described in careful language: the comparison shows, the tradition suggests, the rule states. Using such language keeps the reader honest about what has been established and what remains a matter of judgement.
