Kalaprakasika (1917, p. 71) does not treat a shared birth star as one verdict. It calls a shared star excellent for eight stars (Rohini, Ardra, Magha, Hasta, Vishakha, Shravana, Uttara Bhadrapada, Revati), neutral for eleven, and unsuitable for eight. It then adds order rules: when the two stars are in the same sign, the groom's star should come first, and when a shared star spans two signs, the book says which quarter each partner's should be.
☕ A shared star, then the order of two stars
In the Dinam count, a shared birth star is the 1st step, and the book handles it on its own. It sorts the 27 stars into three lists: for some a shared star is excellent, for some neutral, and for the rest the book counts the match as unsuitable. Which list applies depends only on which star the two people share.
A star covers four quarters (padas), and nine of the 27 stars have quarters in two neighbouring signs. When a shared star is one of these, the book cares which quarter each person's Moon was in. It gives two passages on this, and they read differently: the first says the groom's quarter should be the earlier; the second gives the bride the quarter in the first sign, except when the quarters are split two and two.
The book also has a rule for two different stars in one sign: the groom's star should come before the bride's. It leaves three neighbouring pairs out of that rule, and lists eight stars after which the groom's star may be the very next one.
Nava Panchangam now matches two charts by these ten poruthams: sign in and open Marriage matching at navapanchangam.com/matching for a Nava verdict. This page explains the rule as the book gives it.
The three lists, and the order rules
- Excellent: Rohini, Ardra, Magha, Hasta, Vishakha, Shravana, Uttara Bhadrapada, Revati
- Neutral: Ashwini, Krittika, Mrigashira, Punarvasu, Pushya, Purva Phalguni, Uttara Phalguni, Chitra, Anuradha, Purva Ashadha, Uttara Ashadha
- Unsuitable: Bharani, Ashlesha, Swati, Jyeshta, Moola, Dhanishta, Shatabhisha, Purva Bhadrapada
- A shared star in two signs, first passage: the groom's quarter should be the earlier
- A shared star in two signs, second passage: the bride's quarter in the first sign, the groom's in one of the other sign's; if the quarters split two and two, the first sign is the groom's
- Two stars in the same sign: the groom's star should come before the bride's
- Left out of that rule: Bharani – Krittika; Dhanishta – Shatabhisha; Pushya – Ashlesha
- The groom's star may be the next one after the bride's when hers is: Ashwini, Krittika, Mrigashira, Magha, Hasta, Swati, Purva Ashadha, Shatabhisha
Frequently Asked Questions
Can bride and groom have the same birth star?
Kalaprakasika does not give one answer for all stars. It calls a shared star excellent for eight stars, neutral for eleven, and counts the match unsuitable for eight. The lists are on this page.
Which shared birth stars does the book call excellent?
Rohini, Ardra, Magha, Hasta, Vishakha, Shravana, Uttara Bhadrapada, Revati.
What if the shared star spans two signs?
Then the book looks at the quarter (pada) each person was born in. One passage says the groom's quarter should be the earlier. A later passage gives the bride the quarter in the first sign, and the groom the first sign only when the quarters split two and two. The two passages read differently.
What if the two stars are different but in the same sign?
The book says the groom's star should come before the bride's. It leaves three pairs out of that rule, and lists eight stars after which the groom's star may be the very next one.
From the source
Which stars span two signs, the two passages side by side, and what this page leaves out.
🧮 Which stars span two signs
This is arithmetic, not a table from the book: the 27 stars have 108 quarters and each sign holds nine, so nine stars cross a sign boundary.
- One quarter in the first sign: Krittika, Uttara Phalguni, Uttara Ashadha
- Two and two: Mrigashira, Chitra, Dhanishta
- Three quarters in the first sign: Punarvasu, Vishakha, Purva Bhadrapada
Our reading: the second passage's wording (the first sign's quarter for the bride, "any of the remaining three" for the groom) fits the first group. The book does not spell out the third group.
📖 The two passages, as the book prints them
Page 71 first says that for a shared star in two signs "the stellar quarter of the bridegroom should be the earlier". A few lines later it says "the stellar quarter belonging to the first sign should be that of the bride", any of the other sign's quarters may be the groom's, and "if the stellar quarters be equally divided between the two signs, the sign for the first two should be that of the bridegroom" (p. 72). The first passage and the equal-split case put the groom first; the one-quarter case puts the bride first. These pages print both and do not choose.
Our reading of the eight-star list: in each case the next star can fall in the same sign, so it reads as a relaxation of the same-sign rule just above it. The book places it there without saying so.
✂️ What this page leaves out
The book attaches an outcome to the wrong order in each rule. This page says only which order the book counts as favourable. A shared star is the 1st step of the Dinam count; the series starts at the ten poruthams overview.
