# What a kundli shows about compatibility, and why love goes wrong

> A chart shows how you attach and which periods strain a partnership. It does not show whether the person across from you is kind.

A kundli shows how a person attaches, what they are drawn to, what they will
tolerate, and which stretches of life tend to put a partnership under strain.
Compared against a second chart, it shows where two temperaments will rub. That
is genuinely useful and it is the honest limit. A chart cannot tell you whether
the person across from you is kind, honest or available, and none of the twelve
houses will do your judging for you.

The second thing worth saying at the start: if your love life has been hard, the
chart is very unlikely to be the reason. Most of what breaks relationships is
ordinary and human. Astrology gets asked to carry the blame because blame is
easier to carry when it comes from the sky.

## What is actually read for relationships

**The seventh house.** The house of union, of the partner and of the terms on
which you meet other people. The sign on it, the planets in it, and above all
where its owner sits.

**Venus.** The significator of love, attraction and what pleases you. Venus
describes your taste and your capacity for closeness, not a person who will
arrive.

**Jupiter.** In a woman's chart, tradition reads Jupiter for the husband, as it
reads Venus for the wife in a man's. This is an old convention from an old
society and I say so when I use it. It still reads well for what a person looks
for in a partner.

**The Moon.** How you feel and how you are soothed, which in daily life matters
more to whether two people can live together than anything in the seventh house.

**Mars and Saturn.** Mars for friction, heat and the way arguments go. Saturn for
duty, distance, delay and the long form of commitment.

**The second, fourth and twelfth houses.** Family, home and the bed, which is to
say the actual shape of a marriage rather than its idea.

## Comparing two charts

When two charts are compared, what tradition looks at is where one person's
planets fall in the other's houses, and how the two seventh houses and the two
Moons relate. Tradition reads a person whose Venus falls on your seventh house
as an easy first attraction. Whether that fit survives ten years is a different
question, and the Moons and the Saturn contacts say more about it.

Guna Milan, the count out of thirty-six that families ask for, is a smaller
instrument than its reputation. It compares the two Moons and their nakshatras
and nothing else, and it was designed to screen arranged proposals quickly in a
world with no other information. A high score is not a marriage and a low score
is not a refusal. I use it, and I do not decide on it alone. If it is the only
thing an astrologer looks at before advising a family to break a match, that is
a failure of the astrologer, not a feature of the method.

Mangal dosha deserves the same treatment. Mars in certain houses counted from
the rising sign, the Moon or Venus is read as adding heat and friction to a
marriage. It is extremely common, it has a long list of classical conditions that
cancel it, including the plainest one where both charts carry it, and it has been
used in this country to frighten more families than any other single word in
astrology. I have written about the same problem with delay in
[Saturn and marriage](/learn/saturn-and-marriage).

## Transits: shared weather, personal ground

Transits are where the old page at this address spent most of its words. They are
worth less than they are made to seem, for a simple reason: a transit is shared
by everyone. When Saturn moves into a sign it moves into that sign for the entire
planet at once. Millions of people share it and their relationships do not all
change together.

What transits do is set the weather. Tradition watches Saturn passing over the
seventh house or over the Moon, and reads it as a period asking for patience and
often coinciding with distance or strain. Jupiter's passage over the seventh is
read as the easier one, and is a common time for matches to be settled. Rahu and
Ketu on the axis of the first and seventh houses are read as unsettling and
frequently coincide with unusual attachments.

The reason two people experience the same transit differently is the birth chart
underneath it. Weather is shared, ground is not. Anyone reading you a transit
without your chart is reading you the weather.

## Why a love life fails, plainly

Since the old page promised astrological reasons, here are the ones I think are
honest, and here is where I stop.

The chart can show a repeating pattern. A person who keeps choosing partners who
are unavailable, or who cannot stay when things settle down, will often have that
tendency visible in the chart, and seeing it named on paper can be the thing that
finally lets them look at it. It can show periods that are structurally hard,
where the demands on your time and health leave nothing for a relationship. It
can show a genuine mismatch of temperament between two people who like each
other very much.

What it cannot show, and what usually decides the matter: whether either of you
tells the truth, whether you can apologise, whether the families will interfere,
whether you married the person or the wedding, and whether you are both doing the
unglamorous daily work. No dosha explains contempt. No transit explains a person
who does not call.

And I will not tell you that a chart says you will marry, or that you will marry
in a particular year, or that your marriage will fail. Tradition indicates a
tendency and a period. It does not decide a life, and the reading that pretends
otherwise takes something from you that you should keep.

## Questions people ask

**Can astrology tell me if we are compatible?**

It can tell you where two temperaments fit and where they will grind, and which
periods tradition reads as harder on the two of you. It is a real input and a
partial one. It cannot substitute for knowing the person. Use it the way you
would use an honest opinion from someone who knows you both, not as a verdict.

**Our Guna Milan score is low. Should we call it off?**

No, not on that alone. The score comes from the two Moons and nothing else, and
the rest of both charts is unread until someone reads it. A low score is not a
prediction about a marriage, and the tradition itself does not treat it as one.
If a family is being pushed towards refusal on a number, ask for the whole
comparison.

**Is my Mangal dosha the reason I am not married?**

Almost certainly not on its own. It is common, it has several classical
cancellations, and marriage timing turns on much more than one placement. If
this is what you have been told and it has been sitting on you, bring the chart
and let us look at the whole of it. A [focused reading](/services) is the right
size for exactly this question.
