The kundali lines on a biodata, and the one fact behind most of them

A marriage biodata is the one- or two-page profile families exchange before a first meeting: name, education, work, family, and often a photograph. Many biodatas, in Hindi, Marathi, Gujarati and English alike, also carry a short block headed "Kundali details" or "Horoscope details". A typical block reads like this: Rashi (Moon sign), Nakshatra (birth star) with its charan, Lagna, Nadi, Gan, and Manglik: yes or no. Some add the gotra and the family deity. Those come from the family, not from the birth chart, and this guide leaves them aside.

Most of the chart lines come from one fact: where the Moon stood at the moment of birth. Vedic astrology divides the Moon’s path into 12 signs, the rashis, and into 27 birth stars, the nakshatras. The Rashi line names the sign the Moon was in. The Nakshatra line names the star, and the charan names which quarter of that star. Nadi and Gan are not separate measurements at all: each is a fixed label of the birth star.

Two lines are different. The Lagna is the sign rising on the eastern horizon at the birth time and place, so it rests on the clock, not on the Moon. The Manglik line reads where Mars sits in the full chart. Those two need the exact birth time. The rest need only the Moon’s position, which moves much more slowly, so a rough birth time usually gives them correctly.

That split decides what a biodata can tell you, how far each line can be trusted, and what kundali matching needs from it. The sections below take the lines one at a time.

• From the Moon’s position: Rashi, Nakshatra, charan, Nadi, Gan.
• From the exact birth time and the full chart: Lagna, Manglik.
• From the family, not the chart: gotra, family deity and similar lines.

Rashi, Nakshatra and charan: the lines matching reads

Rashi on a biodata means the Moon sign, the chandra rashi. It is not the Sun sign of a newspaper horoscope. A Western horoscope uses a different zodiac, so its Sun sign is often the next sign along, and a biodata that prints a Western Sun sign under "Rashi" has filled in the wrong line. Our guide to Moon sign, Lagna and Sun sign explains the three signs side by side.

Nakshatra is the birth star, the janma nakshatra: one of 27 equal stretches of the sky, each 13 degrees 20 minutes wide. Charan (charaṇa, "foot" or "quarter") is the same thing many charts call the pada: each star is cut into four charans of 3 degrees 20 minutes. The Moon crosses one star in about a day and one charan in about six hours, so the charan is the most time-sensitive of the Moon lines.

The charan matters for a reason families rarely hear: it fixes the Rashi. A sign holds exactly nine charans, two and a quarter stars, so nine of the 27 stars cross from one sign into the next. Krittika’s first charan is in Mesha (Aries) and its other three are in Vrishabha (Taurus). Chitra’s first two charans are in Kanya (Virgo) and its last two in Tula (Libra). For those nine stars the star name alone leaves the Rashi open, and the charan settles it. A biodata that gives the star and charan has, in effect, given the Rashi too.

Ashtakoot matching, the eight-part guna milan, reads only these lines. It compares the two charts in eight tests, the kootas, and scores them out of 36 points; the “gunas” of guna milan are these points. Our 36-gunas guide explains each koota in plain words. Four of the eight kootas read the two birth stars: Tara, Yoni, Gana and Nadi, 21 of the 36 points. The other four read the two Moon signs: Varna, Vashya, Graha Maitri and Bhakoot, 15 points. Since the star and charan fix the sign, the two stars with their charans settle almost the whole score. In a few cases one koota, Vashya, also depends on where within the charan the Moon sits; a star-based calculator then shows a small range instead of one total. The Lagna plays no part in the 36 points.

Lagna: the line that needs the exact birth time

Lagna is the rising sign: the sign on the eastern horizon at the moment and place of birth. It is the first house of the chart, and every other house is counted from it. Families often call it the ascendant.

The Lagna changes fast. The whole zodiac rises once a day, so each sign rises for about two hours on average, and some signs rise faster than others. A birth time that is out by an hour can move the Lagna to the next sign; in that hour the Moon lines usually do not change. That is why a Lagna line is only as good as the birth time behind it. If the time on the biodata is rounded, guessed by a family pandit, or given as "early morning", treat the Lagna line as provisional.

The Lagna does not enter Ashtakoot matching. It matters for reading the chart as a whole, and it is one of the three points from which the Manglik line is counted. A missing or doubtful Lagna therefore leaves the guna score untouched, but it leaves part of the Manglik answer open. Our guide on matching when a birth time is missing goes through what survives without it.

Nadi: a label of the birth star, and the heaviest koota

Nadi (nāḍī, "channel") sorts the 27 stars into three groups of nine: Aadi (first), Madhya (middle) and Antya (last). The groups follow a fixed zig-zag around the zodiac. Ashwini is Aadi, Bharani Madhya, Krittika and Rohini Antya, Mrigashira Madhya, and so on. Because the label belongs to the star, you can check a biodata’s Nadi line in a few seconds against the table below.

Nadi matters because it is the heaviest of the eight kootas: 8 of the 36 points. When the two stars carry different Nadis, the pair scores all 8. When they carry the same Nadi, the pair scores 0 of 8, and that zero is what families call Nadi dosha, unless one of the exceptions below applies. Our calculators then give the 8 points back.

A same-Nadi pair is not the end of the reading. A widely followed set of exceptions cancels the dosha in three cases. It is attributed to the Muhurta texts, the classical works on choosing auspicious times, and no one verse is cited for it. The three cases are: the same Moon sign with different stars; the same star with different Moon signs; and the same star with different charans. All three are read from the Rashi, Nakshatra and charan lines, which is one more reason a biodata should carry the charan. Our Nadi dosha check tests the three cases from the two stars and charans, and the Nadi and Bhakoot guide explains how much weight the zero carries.

Gan: another label of the birth star

Gan, or gana (gaṇa, "group" or "temperament"), sorts the 27 stars into three other groups of nine: Deva (divine), Manushya (human) and Rakshasa (demonic). The names sound like verdicts on a person. They are not. They are classical labels for temperament, and every one of the three groups holds nine of the 27 stars, so one person in three, roughly, carries each.

Like Nadi, Gan is fixed by the star. A biodata that says "Nakshatra: Ashwini" and "Gan: Rakshasa" has made a copying error, because Ashwini is a Deva star. Check the Gan line against the star with the table in our Gana koota guide.

In matching, Gana carries 6 of the 36 points. A Manushya–Rakshasa pair scores 0 and a Deva–Rakshasa pair scores 1, in either order. So many pairs fall into one of these low-scoring combinations that a low Gana score is common. The Gana guide explains how the six points are scored and what a low Gana does and does not decide.

Manglik: the line with the most rules behind it

Manglik means the chart carries Mangal dosha, a placement of Mars. The basic rule counts the house Mars sits in. If that house is the 1st, 2nd, 4th, 7th, 8th or 12th, the chart is called Manglik. That is six houses of twelve, so counted from the Lagna alone about half of all charts qualify.

Many astrologers count from three points, not one: from the Lagna, from the Moon and from Venus. A chart is then Manglik if any of the three counts lands on one of the six houses. Counted that way, most charts carry it: about nine in ten in our own sample of charts. Traditions then differ widely on what cancels the dosha within a single chart, and on which of these counts to use.

So "Manglik: yes" on a biodata is a statement about a rule, and two biodatas can disagree because they used different rules. The useful question is not "yes or no" but "by which count, from which points, with which cancellations". The Manglik line needs the full chart, and the Lagna count needs the exact birth time, so it cannot be checked from the star and charan.

In matching, Mangal dosha is reported beside the guna score, not inside it. The classical rule looks at both charts together: when both carry it, it is treated as balanced between them, and when only one does, both charts get a closer look. Our Mangal dosha guide goes through the houses, the reference points and the cancellations in full.

When two biodatas, or a biodata and your own check, disagree

It happens often, and it rarely means anyone was careless. Four causes cover most of the cases.

The birth time. A time rounded to the hour can move the Lagna, and near the edge of a star it can move the charan, or even the star. Ask for the time as written on the birth record.

The birthplace and time zone. A chart drawn for the wrong city, or with the wrong time zone for a birth abroad, shifts every time-sensitive line. A birth in London entered as Indian time puts the chart hours out.

The zodiac setting. Indian calculators use the sidereal zodiac with a correction called the ayanamsa. Most use the Lahiri ayanamsa, as ours do; a few use others. The difference is small and changes a line only when the Moon or the Lagna sits close to a boundary.

The rule. The Manglik line, more than any other, depends on which count the calculator applies. Two honest calculators can print "yes" and "no" for the same chart.

When the lines disagree, go back to the birth date, time and place and work them out once, with the method stated. Then compare like with like.

Make the lines from a birth time, and check a match from the star

Sending a biodata: Your Moon sign, birth star and Lagna takes one birth date, time and place. Under "For a marriage biodata" it gives the lines a biodata usually carries: the Moon sign, the birth star with its pada (charan), the Lagna, the Nadi, and whether the chart is Manglik by the rule the page states. You can send them with a link that lets the other family check the match. The link carries only the birth star and pada, never the birth date, time or place. Nothing you type on the page is stored.

Receiving a biodata: check the lines first. Does the Nadi match the star? Does the Gan? Is the Rashi a Moon sign, consistent with the star and charan? Ashwini to Krittika charan 1 is Mesha, and each sign after it holds the next nine charans. Then open the link if one was sent, or our star-based match if not. With the other side’s star and pada filled in, you enter only your own, and the page scores the eight kootas from the two stars. For the Manglik comparison, both full birth details are needed; the same page has a full match for that.

Practical takeaway: read a biodata’s kundali block in two halves. The Moon half (Rashi, Nakshatra, charan, Nadi, Gan) is checkable from the star and carries almost all of the matching score. The clock half (Lagna, Manglik) rests on the exact birth time and on which rule was used, so ask how it was computed before you weigh it.

To go further with Jyothshi Ji, give the chat the birth date, time and place, or pick a saved chart, and ask what the lines mean together.

• Charan is the same as pada: one quarter of a birth star.
• Nadi and Gan are fixed by the birth star; a mismatch is a copying error.
• The Lagna and Manglik lines need the exact birth time; the guna score does not need the Lagna.
