Deva

The ganas are a threefold classification of the twenty-seven nakshatras, the lunar mansions of Indian astronomy, into deva, manushya and rakshasa, divine, human and demonic. Deva gana covers nine of the twenty-seven, among them Ashwini, Mrigashira, Punarvasu, Pushya, Hasta, Swati, Anuradha, Shravana and Revati, and the temperament it denotes is gentle, refined, generous and inclined to serve others; the classical descriptions associate it with sattva, the clear and balanced of the three gunas. The classification is not about the deity of the nakshatra but about the disposition of a person born under it, and its principal use is practical rather than descriptive: it is one of the twelve kootas or points of agreement in the Ashtakoota system by which the compatibility of a prospective bride and groom is assessed in much of India.

The classification is set out, along with the rest of nakshatra based matching, in the Brihat Parashara Hora Shastra, the foundational compendium of Vedic natal astrology traditionally ascribed to the sage Parashara. Within the gana koota, worth six of the Ashtakoota system's thirty-six points, a Deva-Deva pairing scores the full six, a Deva-Manushya pairing scores five, and a Deva-Rakshasa pairing scores zero, the weakest outcome the koota allows; this last rule is the one most often cited in popular accounts of the system and the one most often misread as a judgment on a person's character rather than a rule about compatibility. The word deva itself comes from a Sanskrit root meaning to shine, the same root that gives Latin deus and English divine.

The gana is not a description that stands on its own. It exists because it is one of the factors compared when two horoscopes are set beside one another in the ashtakuta method, the eight-part reckoning used across much of North Indian jyotisha to assess the fit between two people before a marriage. Gana kuta is one of those eight factors, and it is weighted at six points, among the heavier of the eight. The comparison is made not between the two people but between their birth nakshatras, and the gana of each nakshatra supplies the value.

Nine of the twenty seven nakshatras are assigned to deva gana: Ashwini, Mrigashira, Punarvasu, Pushya, Hasta, Swati, Anuradha, Shravana and Revati. The distribution is even, nine to each of the three ganas, and it does not follow the sign boundaries, so two people born under the same rashi may fall into different ganas and two born under different rashis may share one.

Two things are worth saying plainly about how this is used. The first is that gana kuta is one factor among eight and is not read alone; a practitioner weighing a match considers the whole set and the wider chart, and a single low score is not treated as decisive. The second is that this is living practice, carried out today by families and by professional jyotishis, not a historical curiosity. It is described here rather than recommended or instructed, and anyone wanting a reading of an actual chart should go to someone who does this work.
