Nakshatra matching: talk to an astrologer about your birth star compatibility
Most of a Vedic match is built on the two birth stars, and North and South India group those stars in the same way but under different names.

I am Rohini and he is Hasta. The family astrologer says our nadi or rajju does not match. What does that mean?
Rohini and Hasta sit in different nadi groups but the same rajju group in some lists. Please share both birth details so I can check the padas, the exceptions and the rest of both charts.
Short answer
Nakshatra matching compares the two birth stars, the 27 lunar mansions the Moon passes through, for nadi, gana, yoni, rajju and vedha. Prasna Marga bases 16 of its 23 agreement items on the stars. A failed star test is read with its exceptions and with both full charts. On Kismo, verified Vedic astrologers check both birth stars by chat or call, online from anywhere.
What are the key facts about compatibility with partner?
| Answer | |
|---|---|
| What it is | Agreement between two birth stars (janma nakshatra), also called star matching or nakshatra porutham |
| Main star tests | Nadi, gana, yoni, rajju and vedha, plus dina and mahendra in the South |
| Heaviest test | Nadi, worth 8 units in Raman's Muhurtha 1 |
| What an astrologer checks | Each test, then whether an exception applies, then both full charts |
| What to bring | Both birth stars if known, or both dates, times and places of birth |
| Session on Kismo | From ₹15 a minute, 5 free minutes in the first session, online from anywhere in India and abroad |
What does an astrologer check in a nakshatra match?
- Nadi. Raman's Muhurtha splits the 27 stars into three groups of nine and wants the couple in different groups, and never both in the middle one 1.
- Gana. Prasna Marga sorts the stars into divine, human and demonic groups and reads the same gana as highly favourable 2.
- Yoni. Raman assigns each star an animal and a sex, and avoids hostile pairs such as cat and rat or cow and tiger 1.
- Rajju and vedha. Raman groups the stars into five body parts and wants the couple in different groups, and lists 13 star pairs that afflict each other 1.
- The exceptions. Raman allows nadi to be read again by the quarter of the star, the pada, when the star-level test fails 1.
What changes the answer in a nakshatra match?
- Whether you both have the same star. Prasna Marga permits it for 15 of the 27 stars and lists 12 where it is not advised 2.
- Which pada each Moon is in. A nadi that fails by star can pass by pada in Raman's method, so the exact quarter matters 1.
- Whether your astrologer follows a North or South Indian list. The same star groups carry different names, and different weight, in the two traditions.
- Whether other agreements hold. Raman says rajju need not be considered when graha maitri, rasi, dina and mahendra are present 1.
How many couples pass the main nakshatra tests?
About six couples in ten pass nadi, rajju and vedha together. The shares below count all 729 ordered pairs of birth stars, using Raman's groupings, with each star equally likely.
| Calculated fact | Share of couples |
|---|---|
| Clear nadi, rajju and vedha together | 59.3% |
| Both in the middle (pitta) nadi, the case Raman never allows | 11.1% |
| Same rajju group | 21.0% |
| Same rajju, but clear on nadi and vedha | 6.6% |
| A vedha pair | 3.6% |
| Both in the siro (head) rajju | 1.2% |
One star has no vedha partner in Raman's list of 13 pairs: Chitra 1. Prasna Marga instead makes Mrigashira, Chitra and Dhanishta a group of three that repel each other 2.
What do the classical texts say about matching birth stars?
Prasna Marga, the Kerala text, makes the birth star the base of matching. Its chapter on compatibility opens by saying agreement is judged from the birth stars 2. Of its 23 items, 16 come from the stars 2.
Gana sets temperament. Prasna Marga reads the same gana as highly favourable, a divine boy with a human girl as fairly good, and a human boy with a demonic girl as a pair to avoid 2. Raman's notes link the three ganas to sattvic, tamasic and rajasic natures 2.
Prasna Marga gives a way around one gana clash, a human-gana boy with a demonic-gana girl. It lets that clash be ignored if the stars of both ascendants agree, or the Moon's navamsha lords' stars do, or stree deergha holds 2.
The texts admit open questions. Prasna Marga notes that Brihaspati gives Chitra the tiger as its yoni, while Muhurta Ratna gives it the lion, and leaves the choice to the learned 2.
| Test | What it compares | Weight or rule | Source |
|---|---|---|---|
| Nadi | Three groups of nine stars | 8 units; never both in the middle group | 1 |
| Yoni | The animal of each star | 4 units; hostile animals avoided | 1 |
| Gana | Divine, human, demonic | Same gana highly favourable | 2 |
| Rajju | Five body-part groups | Couple should be in different groups | 1 |
| Vedha | 13 afflicting star pairs | Couple should not form a pair | 1 |
Why do North and South Indian astrologers use different names for the same star test?
North and South Indian lists use the same star groups under swapped names. The three groups of nine that Raman's Muhurtha calls nadi appear in Prasna Marga as rajju 12. The five body-part groups Raman calls rajju appear in Prasna Marga as the divisions of vedha dosha 12.
| Star grouping | Raman, Muhurtha (1948) | Prasna Marga (Kerala) |
|---|---|---|
| Three groups of nine stars | Nadi: vata, pitta, kapha 1 | Rajju; the middle group is madhyama rajju 2 |
| Five body-part groups | Rajju: pada, kati, nabhi, kantha, siro 1 | Divisions for vedha dosha 2 |
| Star pairs that repel | Vedha, 13 pairs 1 | Vedha stars, with Mrigashira, Chitra and Dhanishta as a three-way group 2 |
Kerala still matches by the 27 stars. A retired professor quoted by The News Minute says the star system was first used to tell time, and astrologers added marriage rules later 3. Ask your astrologer which list they use before comparing two reports.
What do people get wrong about this?
Belief: Same nakshatra couples can never marry.
Prasna Marga permits the same birth star except for 12 named stars, such as Rohini, Bharani and Hasta 2.
Belief: Nadi dosha cannot be removed.
Raman's Muhurtha checks nadi again by pada when the star-level test fails, and lists conditions under which the nadi flaw can be ignored 1.

Questions people ask
Which nakshatras are compatible with my nakshatra for marriage?
The stars compatible with yours are those in a different nadi group, a different rajju group and not your vedha pair, plus a friendly gana and yoni 14. About six in ten random star pairs clear nadi, rajju and vedha together. An astrologer can list the stars that suit yours and check the padas too.
What is rajju porutham and why does it matter so much in South India?
Rajju porutham checks that the two birth stars sit in different groups, and South Indian families give it heavy weight. In Prasna Marga, rajju means the three groups of nine stars, the same grouping North India calls nadi. Ask your astrologer which list they mean, because the two traditions swap the names.
Can a manushya gana boy marry a rakshasa gana girl?
Prasna Marga advises against a human-gana boy with a demonic-gana girl, but it gives exceptions for exactly this pair. The clash can be ignored if the ascendant stars agree, if the Moons' navamsha lords' stars agree, or if stree deergha holds. Ask an astrologer to check these before treating the gana result as final.
What is yoni matching in nakshatra compatibility?
Yoni matching gives each birth star an animal and a sex, and checks whether the two animals are friendly. Raman's Muhurtha gives it 4 units and avoids hostile pairs such as cat and rat or horse and buffalo. It is read as the physical side of the match, alongside the other star tests.
How much does it cost to have our birth stars matched on Kismo?
Having your birth stars matched on Kismo costs the astrologer's per-minute rate, from ₹15 a minute, billed per started minute. Kismo is an app where you talk to verified Vedic astrologers by chat or call, in 16 languages. Your first session has 5 free minutes and no card is needed.
We were told our stars clash and only a costly remedy can fix it. Is that a red flag?
Yes, a costly remedy offered as the only fix for a star clash is a red flag. The texts themselves give exceptions for nadi, gana and rajju that cost nothing to check 14. Get a second opinion before paying for any ritual. On Kismo, misconduct such as pressure to pay is handled by a person.
