Uttara Ashadha and Shatabhisha nakshatra matching

Four of the eight kootas — Tara, Yoni, Gana and Nadi — are settled by the two birth stars alone, before anyone asks about a pada; the other four are read from the Moon rashi, which a pada can move. For Uttara Ashadha with Shatabhisha that leaves 2 of the eight at full marks — Bhakoot and Nadi — and 6 carrying a deduction: Gana (0 of 6), Graha Maitri (3 of 5), Tara (1.5 of 3), Yoni (1–3 of 4), Vashya (0–1 of 2) and Varna (0 of 1). The heaviest of them is Gana, where Shatabhisha: Rakshasa · Uttara Ashadha: Manushya gives 0 of 6.
Two birth stars are not enough for this pair. Uttara Ashadha runs from Sagittarius into Capricorn after pada 1, and Varna, Vashya, Graha Maitri and Bhakoot are all read from the Moon rashi rather than from the star, which puts 15 of the 36 guna on that boundary — so the total follows, anywhere from 19.5 to 24.5 of 36 depending on the padas. At 5 guna the swing sits above the median of 2, in a range reaching 14 at its widest.
Koota by Koota
All eight kootas for Uttara Ashadha and Shatabhisha, taken at pada 1 each. Two columns because Varna and Gana can score differently by direction where the other six cannot: Varna and Gana differ between them.
| Koota | Uttara Ashadha bride | Shatabhisha bride | What it reads |
|---|---|---|---|
| Varna / 1 | 0 | 1 | Shatabhisha: Shudra · Uttara Ashadha: Kshatriya |
| Vashya / 2 | 0–1 | 0–1 | Shatabhisha: Manav · Uttara Ashadha: Chatushpada |
| Tara / 3 | 1.5 | 1.5 | Counting from Uttara Ashadha: Kshema (4) · from Shatabhisha: Vadha (7) |
| Yoni / 4 | 1–3 | 1–3 | Shatabhisha: Horse · Uttara Ashadha: Mongoose |
| Graha Maitri / 5 | 3 | 3 | Shatabhisha: Saturn · Uttara Ashadha: Jupiter |

| Total / 36 | 20.5–23.5 | 24.5–27.5 | Acceptable |
- Gana, 0 of 6 — Shatabhisha: Rakshasa · Uttara Ashadha: Manushya. The gentle temperament is held to bear the cost of the forceful one unevenly.
- Graha Maitri, 3 of 5 — Shatabhisha: Saturn · Uttara Ashadha: Jupiter. The mental-compatibility koota, and the sign lords fall short of friendship.
- Tara, 1.5 of 3 — Counting from Uttara Ashadha: Kshema (4) · from Shatabhisha: Vadha (7). Half the koota, because the count is unfavourable in one direction only.
- Yoni, 1–3 of 4 — Shatabhisha: Horse · Uttara Ashadha: Mongoose. The middle of this koota, where tables give one, two or three guna.
- Vashya, 0–1 of 2 — Shatabhisha: Manav · Uttara Ashadha: Chatushpada. The middle of this koota: tables put a pair like this anywhere between half a guna and one.
- Varna, 0 of 1 — Shatabhisha: Shudra · Uttara Ashadha: Kshatriya. A deliberately one-way test on rank, failed in this direction. It is one point of thirty-six.
Half-guna figures are exact rather than rounded. Each koota’s rule is set out in full on Uttara Ashadha’s table and Shatabhisha’s.
All Sixteen Pada Combinations
Uttara Ashadha runs Sagittarius 26°40′ – Capricorn 10°00′ and Shatabhisha runs Aquarius 6°40′ – 20°00′ — two arcs 13°20′ wide, each divided into four padas of 3°20′, which puts the two Moons anywhere between 26°40′ and 53°20′ apart. Every cell below holds two totals: Uttara Ashadha as bride first, Shatabhisha as bride second. The cells are not all the same, which is the point of printing them — 15.5 at the lowest and 24.5 at the highest.
| Uttara Ashadha ↓ / Shatabhisha → | Pada 1Aquarius | Pada 2Aquarius | Pada 3Aquarius | Pada 4Aquarius |
|---|---|---|---|---|
| Pada 1Sagittarius | 20.5 / 24.5 | 20.5 / 24.5 | 20.5 / 24.5 | 20.5 / 24.5 |
| Pada 2Capricorn | 15.5 / 19.5 | 15.5 / 19.5 | 15.5 / 19.5 | 15.5 / 19.5 |
| Pada 3Capricorn | 15.5 / 19.5 | 15.5 / 19.5 | 15.5 / 19.5 | 15.5 / 19.5 |
| Pada 4Capricorn | 15.5 / 19.5 | 15.5 / 19.5 | 15.5 / 19.5 | 15.5 / 19.5 |
Strict reading of the two disputed kootas throughout. The generous reading of Yoni and Vashya adds 3 guna to every cell. All sixteen combinations clear the conventional threshold of 18. Dimmed cells fall below it; the nakshatra finder returns the pada from a birth date, time and place.
The Two Doshas, and Whether They Are Cancelled
The two heavy kootas, checked with their cancellations. Neither gives a partial score, so each is worth 8 and 7 guna outright or nothing at all.
Nadi Koota — 8 of 8
Uttara Ashadha is Antya (Kapha) and Shatabhisha is Adi (Vata). Different nadis take the full eight guna, and since Nadi alone is more than a fifth of the total, this pair starts from a position 108 of the 351 pairs never reach.
Bhakoot Koota — 7 of 7 at pada 1
In 12 of the sixteen pada combinations, the two Moon signs stand at one of the three forbidden distances and Bhakoot gives nothing. The commonly cited cancellation covers each of those cells: Jupiter and Saturn are mutual friends in the natural friendship table.
A cancellation is relief, not a score adjustment — the koota still reads zero above. The doshas Ashtakoot does not test for are a separate question — Mangal dosha among them.
Two Tests Outside the 36
Two tests the eight kootas leave out, both settled by the distance between the two stars: Uttara Ashadha to Shatabhisha is 4 and back is 25, counting inclusively.
- Mahendra — present. 4 stars between them, against a favourable set of 4, 7, 10, 13, 16, 19, 22 and 25. 108 of the 351 pairs land on one of those.
- Stri-Dirgha — satisfied one way. The count from the bride's star should pass nine — 4 with Uttara Ashadha as bride, 25 with Shatabhisha — and 135 pairs clear it both ways against 216 that clear it one way. It holds with Shatabhisha as the bride and not with Uttara Ashadha.
Neither test touches the 36. Muhurta nature is a different question again — Uttara Ashadha is Dhruva / Sthira (fixed), Shatabhisha is Chara (movable) — and it governs what each star suits doing, not who it marries.
How the Pair Ranks on Each Side
The same 24.5 of 36 reads differently from each side, because each star is being compared with a different 27: 9th place in Uttara Ashadha's table, 8th in Shatabhisha's. Both positions can be checked by counting rows there — the figures are the ones those tables print.
In Uttara Ashadha’s table
9th of 27
Shatabhisha scores 24.5 there outright. Uttara Ashadha’s 27 partners run from 9.5 to 31 with a median of 22, so this one sits above the middle of what Uttara Ashadha can reach — all 27 rows.
In Shatabhisha’s table
8th of 27
Uttara Ashadha scores 24.5 there, level with 1 other partner. Shatabhisha’s 27 partners run from 9.5 to 28 with a median of 21.5, so this one sits above the middle of what Shatabhisha can reach — all 27 rows.
What This Total Is Not
One number cannot carry a marriage. Ashtakoot reads a single point from each chart — the Moon — so two people born hours apart with the Moon in Uttara Ashadha score identically here whatever else their charts do. The seventh house and its lord, Venus, Mars and Mangal dosha, and the dasha each partner is running are all outside it, and any of them can matter more than the difference between acceptable and the band above.
Written rather than computed, and worth the longer read: what the Navamsa adds that Guna Milan cannot and what a birth date alone can and cannot settle. The full profiles of the two stars — deities, symbols, temperament, the syllables used for naming — are on the Uttara Ashadha page and the Shatabhisha page.
