Compatibility Doshas

What this analyses

The traditional Vedic marriage-compatibility process has two layers:

Ashtakoota — the 36-point matching score (already in the Synastry feature).
Doshas — five specific incompatibility patterns that, if present and uncancelled, weigh heavily even when Ashtakoota looks good.

This feature handles layer 2. It evaluates five doshas, applies the classical cancellation rules, and returns a verdict per dosha plus an overall summary.

How to find it

Features menu → 💑 Compatibility Doshas. Pick a partner from your saved-charts list (you must have both your chart and the partner's chart saved).

The five doshas

1. Manglik Dosha

Rule: Mars in 1, 4, 7, 8, or 12 from either Lagna or Moon in either chart.

Cancellation: If both partners are Manglik, the dosha cancels — they neutralise each other. Some traditions also accept Mars exalted (Capricorn) or in own sign (Aries / Scorpio) as neutralising; this version keeps the rule strict.

Classical reasoning. Mars in any of these "kuja-dosha" houses is associated with marital friction, premature widowhood (in older literature), or hot-tempered conflict.

2. Nadi Dosha

Rule: Both partners' Moon-nakshatras share the same Nadi (Adi / Madhya / Antya).

Cancellation: If both have the exact same nakshatra (number 1-27), many traditions cancel Nadi dosha. KarmaWheel applies that exemption.

Classical reasoning. Nadi correlates with the three Ayurvedic doshas (Vata / Pitta / Kapha). Same Nadi means same biological-energy type — the union is said to lack the complementary balance, and is the most-cited dosha against compatibility.

3. Bhakoota Dosha

Rule: Moon-signs are 6 or 8 apart in either direction (Shashtashtaka).

Cancellation: If the two charts share the same nakshatra-lord, the dosha is cancelled.

Classical reasoning. Sign-distance 6/8 is the classical "house of obstacles and sudden change" (8th-house relationship). The shared nakshatra-lord is read as a sufficient karmic alignment to override.

4. Rajju Dosha

Rule: Both nakshatras fall in the same "Rajju" body-zone:

Rajju	Body region
Pada	Foot
Kati	Waist
Nabhi	Navel
Kantha	Throat
Shiras	Head

Cancellation: None applied automatically. Severity ranks: Shiras > Kantha > Nabhi > Kati > Pada.

Classical reasoning. This is a mortality-pattern dosha; same Rajju is read as risk of widowhood or short-life for one partner. Modern practice often de-weights this dosha.

5. Vedha Dosha

Rule: The two nakshatras are paired in the classical Vedha table (mutually-obstructing star-pairs, e.g. Ashwini ↔ Jyeshtha, Bharani ↔ Anuradha).

Classical reasoning. Vedha pairs are said to obstruct each other's energetic flow. This dosha is rarely a deal-breaker on its own but adds friction when stacked with others.

How to read the result

The page is colour-coded:

A red overall band: "Major doshas remain — discuss with an experienced astrologer."
A green overall band: "No major doshas remain after cancellations."

Each individual dosha is then shown:

Light green if absent or cancelled
Light red if PRESENT for the match

Cancellation reasoning is shown explicitly when applied, so you know why a dosha was let off.

How to use it

Use this with the Ashtakoota score and the Synastry analysis, not instead of. A good Ashtakoota match with an uncancelled major dosha (especially Nadi or Manglik) calls for caution; the inverse (weak Ashtakoota but no doshas) is often workable.

For serious decisions, always consult an experienced astrologer. The compatibility tradition is several centuries deep — there are nuances no algorithm captures fully.
