Graha Maitri Koota: Planetary Friendship in Kundli Matching

Graha Maitri koota measures mental and intellectual compatibility by checking the classical friendship between the planetary lords of both partners' Moon signs. It carries 5 of the 36 total gunas in the Ashtakoot system – behind only Nadi (8), Bhakoot (7), and Gana (6), and worth more than Yoni, Tara, Vashya, or Varna on their own. A family scanning a match report often skips straight to the total score and the Nadi/Bhakoot flags, but Graha Maitri quietly does a lot of work underneath that number, and it is worth understanding on its own terms.

What Graha Maitri koota actually checks

Every Rashi (Moon sign) has a ruling planet – Mars for Mesha, Venus for Vrishabha, Mercury for Mithuna, and so on. Graha Maitri looks at the ruling planet of the boy's Moon sign and the ruling planet of the girl's Moon sign, then asks a simple question rooted in Naisargika Maitri, the natural friendship table of classical astrology: do these two planets get along?

The planets' current strength or position in either person's individual chart doesn't come into it here. Graha Maitri koota is fixed, decided purely by which sign each person was born under. Two people born under Karka (Moon-ruled) and Simha (Sun-ruled) inherit the Sun-Moon friendship as part of their compatibility profile, whatever else is happening in their individual horoscopes.

The logic behind it leans psychological rather than physical. Yoni koota looks at physical and sexual compatibility, Gana koota looks at temperament, and Graha Maitri is read as a marker of mental rapport: how easily two people follow each other's reasoning, whether conversations need constant translation, whether one partner's way of thinking wears on the other over years rather than months. It is less about one dramatic clash and more about the small daily exchanges a marriage is actually built from.

The planetary friendship table

Classical astrology assigns each of the seven chart-ruling planets (Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn – Rahu and Ketu don't rule signs, so they sit outside this table) a fixed set of friends, neutrals, and enemies:

Graha Maitri koota takes both Rashi lords, checks each one's stance toward the other from this table, and scores the pair accordingly. When both lords are the same planet, or view each other as mutual friends, the match earns full or near-full marks. When the relationship is one-sided – one planet counts the other a friend, but not vice versa – the score sits in the middle. When both planets regard each other as enemies, Graha Maitri contributes little or nothing to the total. The exact point split can vary slightly by tradition, so the finer breakdown is best read alongside a full match report rather than reverse-engineered from the table alone.

Why it carries so much weight

Five points out of 36 sounds modest until you set it against the rest of the 36-guna Ashtakoot system: Varna is worth just 1, Vashya 2, Tara 3, Yoni 4. Only Gana (6), Bhakoot (7), and Nadi (8) outrank it. That ordering reflects a working assumption in classical astrology – attraction and social fit can carry a couple through the early years of a marriage, but the long stretch runs on how two people actually think together.

A family comparing two match reports side by side will sometimes see a couple score well on Yoni and Vashya but weakly on Graha Maitri, and wonder why the overall number still looks unconvincing. This is usually why. A pair whose Rashi lords are natural enemies can still clear 18 gunas overall, but the report is flagging something worth noticing: on paper, their planetary temperaments pull in different directions, and daily life may need a bit more deliberate effort – better listening, more patience in disagreements – to feel easy. It is one lens on a match, not a verdict, and like the rest of Vedic matching it offers traditional guidance rather than a guarantee of how two people will get along.

How it compares with Gana koota

Families often lump Graha Maitri in with Gana koota, since both get described loosely as "compatibility of nature," but they check different things. Gana koota sorts each partner into Deva, Manushya, or Rakshasa temperament groups based on nakshatra, and scores how those three broad personality types sit together – closer to asking whether two basic dispositions clash. Graha Maitri looks specifically at the planetary lords of the Moon signs and their fixed classical friendship – closer to asking whether two minds process the world in a compatible way. Gana koota can flag friction over energy levels or emotional intensity even when Graha Maitri is strong, and the reverse holds too: a strong Gana score does not guarantee mental ease. The two kootas are simply reading different layers of the same relationship.

Neither should be read alone. A weak Graha Maitri score sitting next to strong Gana, Bhakoot, and Nadi results usually carries less practical weight than the same weak score sitting next to several other weak ones. This is part of why which guna matters most is a more useful question than just counting the total – the pattern across all eight kootas tells you more than any single number does.
