Guna Milan on Your Birth Chart: Ashtakoota Matching with Lahiri Sidereal
Vedic mode on Astro Mate now shows your Moon nakshatra on the Birth Chart page and Guna Milan (Ashtakoota) scores when you match. Here is what the eight kootas mean, and how to read them without forgetting the person.
The chart should speak your language
If you practice jyotisha, a tropical synastry card can feel like the wrong dialect. Same birth data, different vocabulary. You want sidereal signs, Lahiri ayanamsa on the label, and matching scores that follow the tradition you actually use.
Astro Mate's Vedic frame already redrew the wheel and dating synastry in Lahiri sidereal. Two pieces were still missing on the Birth Chart page itself: a clear Lahiri note at the top, and your Moon nakshatra (lunar mansion plus pada) beside the big three. When you unlock compatibility in Vedic mode, the four Western bars step aside for Guna Milan: the Ashtakoota score used in classical kundli matching.
Profiles still come first. Photos, bio, the big three, a real human on the other side of the thread. The chart is the second conversation, the one you open when curiosity outruns the swipe. That is the point of astrology dating: meet someone who makes your chart curious, then let the numbers give you language for what you already felt.
What you see on the Birth Chart page
Open Birth Chart with Vedic (Sidereal) saved in your profile and two details change right away.
The subtitle names the frame: a precise sidereal natal chart calculated with Swiss Ephemeris and Lahiri ayanamsa. Lahiri (Chitrapaksha) is the offset India uses to convert tropical longitudes to sidereal ones. If you have compared charts on other Vedic tools, your signs should look familiar here. We covered why Astro Mate picks Lahiri in Vedic astrology on Astro Mate.
In the saved birth summary card, below Sun, Moon, and Ascendant, you will see Moon nakshatra with its pada (quarter). Example: Pushya, pada 1. Nakshatras divide the zodiac into 27 lunar mansions of 13°20' each. In classical matching, both partners' Moon nakshatras feed the Guna Milan math. Showing yours on the chart page makes that link visible before you ever open a match.
Traditional (Western) charts are unchanged: tropical Placidus, no nakshatra line, synastry still uses the four category bars. Switch frames in profile settings any time.
Guna Milan when you match
In Vedic mode, synastry after a match becomes Guna Milan instead of Spark / Talk / Love / Lasting. One total out of 36 gunas, then eight kootas (categories), each with its own cap. The score is computed from both Moons in the Lahiri sidereal frame: nakshatra, pada, and the Moon signs behind them.
This is the card Alex and Maya get in the dating demo when read sidereally:
Guna Milan
Alex's Moon lands in Pushya, pada 1. Maya's in Shravana, pada 3. Together they score 26 of 36, in the "very good match" band. A strong Gana and Nadi, a clean Bhakoot, and a few kootas that ask for patience (Yoni at zero, Graha Maitri low). That mix is normal. Real pairs rarely max every row.

The eight kootas, in plain language
Ashtakoota means "eight divisions." Each koota adds up to a slice of the 36 gunas. Think of them as separate questions about the same two Moons, not eight reasons to panic.
Varna (1 guna) checks whether the Moon signs sit in a compatible spiritual/social order in the classical scheme. One point when the traditional hierarchy aligns, zero when it does not.
Vashya (2 gunas) looks at mutual influence between sign types (how much one chart "holds" the other in the old animal-and-element groupings). Full points mean the signs fall in friendly influence groups.
Tara (3 gunas) measures auspicious directions between birth stars: counting nakshatras from your Moon to theirs and back. Both directions auspicious earns three; one direction earns one and a half; neither earns zero.
Yoni (4 gunas) maps each nakshatra to an animal symbol and scores instinctive affinity between them. High Yoni is often read as physical chemistry in the old marriage manuals. Low or zero is friction to notice, not a ban.
Graha Maitri (5 gunas) compares the friendship between the rulers of your Moon signs (for example Moon and Saturn, or Venus and Mars). Planetary friendships in jyotisha are directional; this koota captures that chemistry at the lord level.
Gana (6 gunas) classifies temperament into Deva (refined), Manushya (human), and Rakshasa (intense). Same gana or Deva with Manushya scores well; a Rakshasa cross with Deva traditionally scores zero. In dating, read it as pace and intensity, not a moral label.
Bhakoot (7 gunas) watches the distance between Moon signs for dosha positions (classically the 2-12, 5-9, and 6-8 relationships). Zero here is a serious flag in arranged-marriage charts. Astro Mate also applies a standard cancellation when the Moon sign lords are friendly. Seven points means no active dosha.
Nadi (8 gunas) is the largest single bucket. It compares the pulse type (Adi, Madhya, Antya) assigned to each nakshatra. Same nadi scores zero (Nadi dosha, traditionally tied to health and progeny concerns). Different nadis earn all eight.
Add the rows and you get the total. Standard thresholds: below 18 is difficult, 18 to 24 acceptable, 25 to 32 very good, 33 and above excellent. Alex and Maya at 26 sit comfortably in "very good," with clear strengths and one or two rows worth discussing over coffee.
People before gunas
Guna Milan was built for kundli matching: families comparing charts before a wedding. Astro Mate brings it into dating, where you have already seen a face and sent a message. That order matters.
A high total is not permission to ignore red flags in real life. A low Yoni or a Nadi dosha is not a command to unmatch. Consent, communication, safety, and time still outrank any table. The score is a prompt: something to ask about, not a verdict stamped on a stranger.
If you prefer tropical synastry, stay on Traditional. You still get attraction, communication, love, and long-term bars, as in what synastry scores mean when dating. Vedic viewers see Guna Milan against any profile; both charts recompute in your frame. Nobody mixes a tropical Leo with a sidereal Karka and calls it done.
We are also not pretending to be a full Jyotish office. Navamsa and the rest of a wedding kundli packet live with your Jyotishi. Vimshottari dasha now sits on the Birth Chart page. Moon nakshatra on your chart page is an anchor for matching, not a complete nakshatra reading of every planet.
