Nadi, Bhakoot and Gana dosha cancellations

Published 9 Oct 2026

Three kootas in Ashtakoota carry a dosha beyond their lost points: Nadi (8), Bhakoot (7) and Gana (6). Together they are 21 of the 36 points, and most of the disagreement in matching happens here. By the end of this article you will be able to test each dosha against its standard cancellations, see why a cancellation fails when it does, and know which exceptions are school-specific.

Definitions

• Nadi dosha: both Moons fall in nakshatras of the same Nadi (Aadi, Madhya or Antya). Nadi scores 0.
• Bhakoot dosha: counting from one Moon sign to the other gives 2/12, 5/9 or 6/8. Bhakoot scores 0.
• Gana dosha: the Gana pair scores 0 on the bride-by-groom table. With the table used here, that is a Rakshasa groom with a Deva bride, or a Manushya and Rakshasa pair in either direction.
• Cancellation (parihara): a condition under which the dosha is treated as not operating. The koota still shows its score; the cancellation is a judgement recorded beside it.
• Live dosha: a dosha with no cancellation that applies.
• Natural friendship: the fixed (naisargika) planetary friendships of Brihat Parashara Hora Shastra. These are not always mutual.

The method

Work in this order. Bhakoot first, because the Gana cancellation depends on it.

Step 1: Bhakoot dosha and its cancellations

Count inclusively from the groom's Moon sign to the bride's, and back. If the pair is 2/12, 5/9 or 6/8, there is a Bhakoot dosha. Then test, in order:

The mutual-friend test is strict. Friendship in one direction is not enough. Under natural friendship the mutual pairs are:

Pairs such as Moon–Mercury, Moon–Jupiter or Mercury–Saturn fail because one planet sees the other as neutral or an enemy.

Step 2: Gana dosha and its cancellations

Gana dosha exists only when the Gana score is 0. A Deva groom with a Rakshasa bride scores 1 on the table used here, so it is not flagged as a dosha even though it is a weak pair. If the score is 0, test:

"Clean" is meant literally. If Bhakoot is a dosha that was itself cancelled in Step 1, that does not count as clean for Gana. The logic is that one weak area can be carried by a strong one, but two faults leaning on each other do not cancel.

Step 3: Nadi dosha and its cancellations

If both Moons share a Nadi, test:

The first test is narrower than it looks. Because Nadis run in a zig-zag (Aadi, Madhya, Antya, Antya, Madhya, Aadi), two different nakshatras of the same Nadi share a sign only in six signs:

The second test applies only to the nine nakshatras that cross a sign boundary: Krittika, Mrigashira, Punarvasu, Uttara Phalguni, Chitra, Vishakha, Uttara Ashadha, Dhanishta and Purva Bhadrapada.

If both Moons are in the same nakshatra, the same sign and the same pada, no cancellation applies.

Step 4: Read the result

After the tests, the working rule AstroReads uses is: a total of 18 or more out of 36 is acceptable only when no Nadi or Bhakoot dosha is still live. A live Gana dosha costs its 6 points but does not on its own block a match that clears 18. Cancellations do not change the total; they change whether the dosha counts against the match.

Worked example

Example A (groom) and Example B (bride) are fictional births used only to illustrate the method. Example A's Moon is in Virgo, Chitra pada 2. Example B's Moon is in Capricorn, Shravana pada 3. The full Ashtakoota is 17.5 out of 36.

Bhakoot: Virgo and Capricorn

From Virgo to Capricorn is 5; from Capricorn to Virgo is 9. This is a 5/9 Bhakoot dosha.

• Same lord? Virgo is ruled by Mercury, Capricorn by Saturn. No.
• Mutual friends? Saturn counts Mercury as a natural friend, but Mercury counts Saturn as neutral. The friendship runs one way only, so the test fails.

The Bhakoot dosha is live.

Gana: Rakshasa groom, Deva bride

Chitra is Rakshasa and Shravana is Deva. On the bride-by-groom table, a Deva bride with a Rakshasa groom scores 0, so there is a Gana dosha. Note that if the roles were reversed (Deva groom, Rakshasa bride) the score would be 1 and no dosha would be flagged.

• Graha Maitri full? Mercury and Saturn score 4, one short of 5. No.
• Bhakoot clean? No. Bhakoot is itself a live 5/9 dosha.

The Gana dosha is live. This case shows why the order of testing matters: had Bhakoot been clean, Gana would have been cancelled.

Nadi: Madhya and Antya

Chitra is Madhya and Shravana is Antya. Different Nadis, full 8 points, nothing to cancel.

What the astrologer looks at next

On Ashtakoota alone this match reads as weak: 17.5, just under 18, with a live Bhakoot dosha. That is where a calculator stops and an astrologer starts. Reasonable next steps:

1. Check wider Bhakoot exceptions your tradition accepts. Some practitioners also test the lords of the navamsa signs occupied by the two Moons. Here Example A's Moon is in Virgo navamsa and Example B's in Gemini navamsa, both ruled by Mercury. An astrologer who accepts that exception would treat the Bhakoot dosha as cancelled; the strict test used here does not.
2. Consider compound rather than natural friendship. Some astrologers judge the Moon-sign lords by their compound (panchadha) relationship in the actual charts, which can turn Mercury's neutrality towards Saturn into friendship or enmity. This needs both charts and is a judgement call.
3. Read each chart's own marriage promise. Ashtakoota compares two Moons. It does not judge either person's 7th house, its lord, Venus or the running dashas. Both fictional charts carry a conditional marriage promise on their own reading, which needs separate attention.
4. Check Manglik status separately. Both fictional charts are Manglik by placement, and in both the Manglik dosha is cancelled (Mars exalted in Capricorn for Example A; Mars conjunct Jupiter for Example B), so neither chart carries an uncancelled Manglik dosha by the rules applied here. How much weight each cancellation deserves is still the astrologer's call; the Manglik article covers this.

Where traditions differ

North vs South. These three doshas belong to the North Indian Ashtakoota. South Indian practice uses the dasha porutham, where the comparable weight falls on Rajju, Rasi and other poruthams with their own exceptions. Poruthams are not implemented here, and astrologers working in that tradition should apply them separately.

Which Bhakoot pairs are doshas. The usual three are 2/12, 5/9 and 6/8. Practitioners differ on their severity: 6/8 is the most consistently treated as serious, while some regard 2/12 or 5/9 as milder. All three are treated equally here.

Strength of each cancellation. Texts and teachers do not agree on how far each exception goes. The same-lord rule for Bhakoot is widely accepted. The mutual-friendship rule is accepted by many, but some use compound friendship, and some extend the test to navamsa lords, as in the worked example. For Nadi, many astrologers remain cautious about a same-Nadi match even when an exception technically applies, and some treat any match in the same nakshatra as unfavourable whatever the pada. The engine applies the three Nadi exceptions mechanically and leaves that caution to the astrologer.

Nadi exceptions by nakshatra. Some schools and almanacs list particular nakshatras for which Nadi dosha is not applied. These lists differ from source to source and are not applied here.

Gana tables. Some sources score Gana symmetrically, and some give Deva–Rakshasa 0 in both directions. Under the bride-by-groom table followed here, a Deva groom with a Rakshasa bride scores 1 and is not flagged as a dosha. With a symmetric table, that same pair would be a Gana dosha.

Restoring points. Some calculators add the points back when a cancellation applies, which can change the total by 6, 7 or 8 points. Here the total stays as computed and the cancellation is reported next to it, so the astrologer sees the raw score and the exception separately.

The 18-point line. The 18-of-36 threshold is a convention in wide use, not a rule from a classical verse. Using it together with "no live Nadi or Bhakoot" is one reasonable reading; other astrologers weight the doshas differently, and their choices are just as legitimate.

Common mistakes

• Counting one-way friendship as mutual. Mercury and Saturn are the classic trap: Saturn likes Mercury, Mercury is neutral to Saturn.
• Using a cancelled Bhakoot to cancel Gana. One exception should not be stacked on another.
• Forgetting the direction of the Gana table. Swapping bride and groom can create or remove a Gana dosha.
• Applying "same sign, different nakshatra" where it cannot occur. Only six signs contain two same-Nadi nakshatras.
• Treating a cancellation as a clean bill. A cancelled dosha means the fault is not counted against the match. It does not make the pair strong.
