The Nine Grahas

We have been talking about grahas (ग्रह) in every chapter so far. The weekday is ruled by a graha. The nakshatra is ruled by a graha. The rashi is ruled by a graha. We have used them as background, but never given them their own treatment.

This chapter is that treatment. We will look at all nine grahas — the seven luminaries plus the two lunar nodes — with enough depth that you can read any classical reference to a graha and know what is meant. The chapter is long. Treat it as nine short chapters back to back; each graha section can be read independently after the framework introduction.

Why nine?

The Sanskrit word grahaliterally means “seizer” or “grasper” — from the root grah, “to grasp.” The grahas are called this because they were thought to grasp the consciousness of a person, influencing thought and action. It is not the same word as the modern English “planet” (Greek planētēs, “wanderer”) — though both words describe the same celestial bodies, and both reflect a metaphor for observed motion.

The classical list is the navagraha (नवग्रह) — the nine grahas:

1. Surya (सूर्य) — the Sun
2. Chandra (चन्द्र) — the Moon
3. Mangala (मंगल) — Mars
4. Budha (बुध) — Mercury
5. Guru / Brihaspati (गुरु / बृहस्पति) — Jupiter
6. Shukra (शुक्र) — Venus
7. Shani (शनि) — Saturn
8. Rahu (राहु) — the northern lunar node
9. Ketu (केतु) — the southern lunar node

Notice what is and is not on this list. The Sun and the Moon are grahas — even though, by modern astronomy, the Sun is a star and the Moon is a satellite of Earth, neither is technically a planet. Rahu and Ketu are grahas — even though they are not bodies at all, only the two intersection points where the Moon’s orbit crosses the ecliptic. And conspicuously absent: Uranus, Neptune, and Pluto. These were unknown to the ancient world, since they are invisible to the naked eye. They are not part of the traditional navagraha system.

Some modern Vedic astrologers have proposed including Uranus, Neptune, and Pluto as adjuncts to the classical nine. This is a contested move. The classical texts and all traditional ritual practice use the nine, and we will too.

The framework: how to read each graha’s entry

For each graha we will note:

• Identity — Sanskrit name, common alternate names, what the body actually is in modern astronomy.
• Nature (svabhava) (स्वभाव) — what kind of force the tradition associates with this graha.
• Karaka (कारक) — significator. The areas of life this graha represents.
• Rashi rulership (राशि स्वामित्व).
• Exaltation and debilitation (उच्च-नीच) — the rashi and degree where the graha is at its strongest, and where it is at its weakest.
• Friendships (मैत्री) — with which other grahas this one is friendly, neutral, or hostile.
• Day, colour, gem, metal, direction — the ritual associations.
• Mythological identity — the deity identified with the graha and the major story arcs.

Surya — the Sun सूर्य

Identity: Surya is the Sun. Other names: Ravi, Bhanu, Aditya, Bhaskar, Pushan. Modern astronomy: the star at the centre of our solar system.

Nature: Royal, fiery, masculine, sattvic (quality of clarity and goodness), authoritative.

Karaka — significator of: the soul (atman), the self, the father, vitality, leadership, the spine, the heart, government, kings and rulers, the ego, fame, legitimate authority. In medical astrology Surya governs the heart and the eyes (especially the right eye in men, left eye in women).

Rashi rulership: Simha (Leo) — only one rashi.

Exaltation: 10° Mesha (Aries). Debilitation: 10° Tula (Libra). The Sun is strongest in the springtime fire-sign and weakest in the air-sign opposite.

Friendships: Friendly with Moon, Mars, Jupiter. Neutral with Mercury. Hostile with Venus, Saturn, Rahu, Ketu.

Day: Sunday (Ravivara). Colour: red, copper, saffron. Gem: ruby (manik). Metal: copper, gold. Direction: east. Element: fire (agni). Number: 1.

Mythology: Surya is one of the principal Vedic deities, traversing the sky in a chariot drawn by seven horses (representing the seven days of the week, or the seven colours of the spectrum). He is the father of Yama (death), Yamuna (the river), Karna (the Mahabharata hero), Saturn (Shani), and the Ashwin twins. The Aditya Hridaya Stotram from the Ramayana is the principal hymn of praise to Surya, recited at sunrise.

Astronomical period: apparent annual motion of 360° / year ≈ 1° per day. The Sun spends about 30 days in each rashi.

Chandra — the Moon चन्द्र

Identity:Chandra is the Moon. Other names: Soma, Indu, Shashi, Mriganka. Modern astronomy: Earth’s natural satellite.

Nature: Watery, feminine, sattvic, cool, receptive, changing.

Karaka: the mind (manas), emotions, the mother, feminine fertility, water and fluids, the public, memory, taste, peace, comfort, milk, liquids, beverages. Medically Chandra governs the lungs, the breasts, the stomach and digestive fluids, body fluids generally, and the left eye in men / right eye in women.

Rashi rulership: Karka (Cancer) — only one rashi.

Exaltation: 3° Vrishabha (Taurus). Debilitation: 3° Vrishchika (Scorpio).

Friendships:Friendly with Sun, Mercury. Neutral with Mars, Jupiter, Venus, Saturn. Hostile with Rahu, Ketu (because Rahu and Ketu are the eclipse-points that “swallow” the Moon).

Day: Monday (Somavara). Colour: white, silver, pale. Gem: pearl (moti). Metal: silver. Direction: north-west. Element: water (jala). Number: 2.

Mythology: Chandra is the deva of the Moon, said to have 27 wives — the 27 nakshatras, daughters of Daksha — but to favour Rohini, which led to a curse from Daksha causing the Moon to wax and wane. Soma is also the sacred Vedic plant from which the elixir of immortality was extracted; this conflation of plant, drink, and Moon is one of the oldest associations in Indian thought.

Astronomical period: sidereal month 27.32 days. The Moon traverses one nakshatra (~13°20′) per day on average — though, as we have seen, this varies.

Mangala — Mars मंगल

Identity: Mangala is Mars. Other names: Bhauma, Kuja, Angaraka. Modern astronomy: the fourth planet from the Sun.

Nature: Fiery, masculine, tamasic (quality of inertia and force), sharp, energetic, hot.

Karaka: energy, courage, willpower, anger, siblings (especially younger brothers), warriors and soldiers, surgeons, engineers, athletes, blood, muscles, red things, weapons, accidents, surgery, real estate (land). Mars is also the karaka for marriage in some traditions — if afflicted, a person is said to be mangalik, requiring careful matching in marriage astrology.

Rashi rulership: Mesha (Aries) and Vrishchika (Scorpio).

Exaltation: 28° Makara (Capricorn). Debilitation: 28° Karka (Cancer).

Friendships: Friendly with Sun, Moon, Jupiter. Neutral with Venus, Saturn. Hostile with Mercury (and Rahu, Ketu in some lists).

Day: Tuesday (Mangalavara). Colour: red. Gem: red coral (moonga). Metal: copper. Direction: south. Element: fire (agni). Number: 9.

Mythology:Mangala is the deva of war, often identified with Kartikeya / Skanda / Subramanya. He is also called Bhauma (“earth-born”) because of a myth in which he was born from a drop of Shiva’s sweat falling on the earth. Hanuman is considered the protector against Mars’s afflictions and is worshipped on Tuesdays.

Astronomical period: sidereal year 687 days. Mars goes retrograde once every ~26 months for approximately 60–80 days.

Budha — Mercury बुध

Identity: Budha is Mercury. The Sanskrit name shares its root with buddhi (intellect) and the Buddha (“the awakened one”) — though the deity Budha and the Buddha are distinct figures.

Nature:Earthy and airy mixed, neutral gender, rajasic-with-sattva, quick, communicative, adaptable. Mercury takes on the qualities of whichever planets it associates with — it is the most “influenced” of the grahas.

Karaka: intellect, speech, communication, commerce, writing, accounting, scholarship, wit, humour, teenagers and young adults, cousins, friends-as-equals, merchants, mathematicians, programmers, journalists, translators. Medically: nervous system, skin, voice, speech-related anatomy.

Rashi rulership: Mithuna (Gemini) and Kanya (Virgo).

Exaltation: 15° Kanya (Virgo) — Mercury is unique in being exalted in its own rashi. Debilitation: 15° Meena (Pisces).

Friendships:Friendly with Sun, Venus. Neutral with Mars, Jupiter, Saturn. Hostile with Moon (because the Moon is mythologically associated with Tara, Budha’s mother in the most well-known myth).

Day: Wednesday (Budhavara). Colour: green. Gem: emerald (panna). Metal: brass, bronze. Direction: north. Element: earth (prithvi). Number: 5.

Mythology:Budha’s origin myth is one of the most dramatic in the puranic literature. Tara, the wife of Brihaspati (Jupiter), was abducted by Chandra (Moon). The resulting child was Budha — caught in the middle of a feud between his biological father (Moon) and his adoptive father (Jupiter). The myth captures Mercury’s adaptability and dual nature.

Astronomical period:sidereal year 88 days. Mercury goes retrograde three times per year for ~24 days each — the most frequent retrograde of any graha, source of the popular “Mercury retrograde” observation.

Guru / Brihaspati — Jupiter गुरु / बृहस्पति

Identity: Guru is Jupiter. The name gurumeans “heavy, weighty” (and also “teacher”). Brihaspati means “lord of prayer.” Both names refer to the same body. Modern astronomy: largest planet in the solar system.

Nature: Sattvic, masculine, expansive, benevolent, wise. Jupiter is considered the most beneficial of all the grahas.

Karaka:wisdom, knowledge, dharma (righteous duty), teachers, gurus, religion, philosophy, the law, judges, priests, children (especially the first child), husband (in a woman’s chart), wealth and fortune, gold, expansion, abundance, optimism. Medically: liver, fat, the pancreas.

Rashi rulership: Dhanu (Sagittarius) and Meena (Pisces).

Exaltation: 5° Karka (Cancer). Debilitation: 5° Makara (Capricorn).

Friendships: Friendly with Sun, Moon, Mars. Neutral with Saturn. Hostile with Mercury, Venus.

Day: Thursday (Guruvara). Colour: yellow, gold. Gem: yellow sapphire (pukhraj). Metal: gold. Direction: north-east. Element: ether (akasha). Number: 3.

Mythology: Brihaspati is the preceptor of the devas — the celestial guru — counterpart to Shukra, the preceptor of the asuras. The dynamic between Brihaspati and Shukra is a recurring theme in puranic literature, representing the tension between the principles each represents.

Astronomical period:sidereal year ~12 years. Jupiter spends about 1 year in each rashi — making Jupiter’s transit one of the most commonly-tracked annual astronomical events.

Shukra — Venus शुक्र

Identity:Shukra is Venus. The name comes from the root meaning “bright, white, radiant.” Modern astronomy: the second planet from the Sun, brightest natural object in the night sky after the Moon.

Nature: Watery, feminine, rajasic with sattvic overtone, sensual, harmonious, refined.

Karaka:love, marriage, romance, the wife (in a man’s chart), beauty, art, music, dance, poetry, luxury, vehicles, jewellery, perfume, sexuality, feminine companionship, wine, sweets, comfort. Medically: reproductive system, kidneys, semen, the throat.

Rashi rulership: Vrishabha (Taurus) and Tula (Libra).

Exaltation: 27° Meena (Pisces). Debilitation: 27° Kanya (Virgo).

Friendships: Friendly with Mercury, Saturn. Neutral with Mars, Jupiter. Hostile with Sun, Moon.

Day: Friday (Shukravara). Colour: white, light blue, pastel. Gem: diamond (heera). Metal: silver, platinum. Direction: south-east. Element: water (jala). Number: 6.

Mythology:Shukracharya is the preceptor of the asuras (the “anti-gods”) and possessor of the mritasanjivani vidya — the knowledge to revive the dead. The asura-deva struggle, with Shukra and Brihaspati on opposite sides, structures much of puranic narrative.

Astronomical period: sidereal year ~225 days. Venus has the most regular retrograde cycle of any planet — once every 584 days for ~40 days.

Shani — Saturn शनि

Identity: Shani is Saturn. The name comes from the root shanaih“slowly” — for Saturn moves the slowest of all the visible grahas. Modern astronomy: the sixth planet from the Sun, with the prominent ring system.

Nature: Airy, dark, tamasic, slow, cold, masculine.

Karaka: longevity, discipline, hard work, patience, suffering, restriction, justice, karma, old age, servants, the working class, the marginalised, machinery, iron, oil, leather, the dead, asceticism, renunciation. Medically: bones, joints, teeth, the knees, chronic disease, anything degenerative.

Rashi rulership: Makara (Capricorn) and Kumbha (Aquarius).

Exaltation: 20° Tula (Libra). Debilitation: 20° Mesha (Aries).

Friendships: Friendly with Mercury, Venus. Neutral with Jupiter. Hostile with Sun, Moon, Mars.

Day: Saturday (Shanivara). Colour: dark blue, black. Gem: blue sapphire (neelam). Metal: iron, steel. Direction: west. Element: air (vayu). Number: 8.

Mythology:Shani is the son of Surya (Sun) and Chhaya (Sun’s shadow-wife). His piercing gaze is said to bring suffering wherever it falls; the Sun himself is said to have suffered at his son’s gaze. Shani is paradoxically a stern teacher — those who pass through Saturn’s difficult periods are said to emerge with deep capacity for endurance and wisdom. The 7.5-year transit of Saturn through the Moon-rashi (and the rashis on either side of it) is called sade sati (साढ़े साती) and is one of the most-discussed astrological periods.

Astronomical period: sidereal year ~29.5 years. Saturn spends about 2.5 years in each rashi — producing Sade Sati when it transits the rashi before, the same as, and the rashi after the natal Moon-rashi.

Rahu — the northern lunar node राहु

Identity:Rahu is one of the two intersection points where the Moon’s orbit crosses the ecliptic — the northern (ascending) node. Unlike the other grahas, Rahu is not a body. It is a geometric point. But in classical Indian astronomy and astrology it is treated as a graha and given equal weight.

Nature: Shadowy, tamasic, foreign, amplifying, intoxicating, misleading.

Karaka: obsession, illusion, foreign influences, technology, drugs and intoxicants, outsiders, sudden gains, scandals, unconventional behaviour, eclipses, snakes, things hidden in shadow. In modern interpretation: the internet, electronics, space travel, artificial intelligence — anything boundary-crossing or unprecedented.

Rashi rulership: Rahu does not own a rashi formally. Some traditions assign Rahu rulership of Kumbha (Aquarius) by analogy with Saturn.

Exaltation: traditionally Vrishabha (some say Mithuna). Debilitation: traditionally Vrishchika (some say Dhanu). Sources differ.

Friendships:Friendly with Saturn, Venus, Mercury. Hostile with Sun, Moon, Mars. (Reflects the eclipse mythology — Rahu “swallows” the Sun and Moon.)

Day: no specific day, but Saturday treated as ruling day for purposes of Rahu remedy. Colour: dark blue, smoky. Gem: hessonite (gomed). Metal: lead. Direction: south-west.

Mythology: Rahu was an asura who, during the churning of the ocean, disguised himself as a deva to drink the amrita (nectar of immortality). Vishnu beheaded him, but because the nectar had reached his throat he could not die — his head and body separated but both became immortal. The head is Rahu, the body is Ketu. Rahu pursues the Sun and Moon in revenge for their having identified him at the moment of the beheading; when he catches them, an eclipse occurs.

Astronomical period: Rahu (and Ketu) complete one cycle of the zodiac in ~18.6 years, moving in retrograde (opposite direction to the planets) through the rashis. This means the nodal cycle is reverse-direction — Rahu goes from Mesha to Meena (not Mesha to Vrishabha as the planets do).

Ketu — the southern lunar node केतु

Identity: Ketu is the southern (descending) lunar node, exactly 180° opposite to Rahu at all times. Like Rahu, it is a geometric point, not a body.

Nature: Shadowy, tamasic, detaching, spiritual, dissolving.

Karaka: spirituality, moksha (liberation), occult knowledge, past-life karma, renunciation, things lost, accidents, hidden wisdom, introspection. Where Rahu pulls outward into attachment, Ketu pulls inward into detachment. In a sense Ketu is the photographic negative of Rahu — both liminal, both unconventional, but in opposite directions.

Rashi rulership: some traditions assign Ketu the rulership of Vrishchika (Scorpio) by analogy with Mars.

Exaltation: traditionally Vrishchika. Debilitation: traditionally Vrishabha. Again, sources differ.

Friendships: similar pattern to Rahu — friendly with Saturn, Venus, Mercury; hostile with Sun, Moon, Mars.

Colour: red-brown, smoky. Gem: cat’s eye (lehsunia). Metal: lead, bronze.

Mythology: Ketu is the body of the beheaded asura whose head is Rahu. The body, like the head, became immortal because the amrita had touched it. Ketu is therefore associated with the headless, the bodily-without-mind, the karmic remainder.

Astronomical period: exactly the same as Rahu; they move together as a fixed pair, always 180° apart.

Beneficial vs malefic grahas

Classical texts sort the nine grahas into two groups by general nature:

• Natural benefics (शुभ ग्रह): Jupiter, Venus, Mercury (when not afflicted), waxing Moon. These tend to give favourable results.
• Natural malefics (पाप ग्रह): Saturn, Mars, Sun, waning Moon, Rahu, Ketu. These tend to give challenging results.

These are natural classifications. In a specific chart, the same graha can become a functional benefic or malefic depending on which houses it owns and occupies. A natural benefic can become functionally malefic for a particular ascendant; a natural malefic can become a yogakaraka (combiner of benefic effects). This functional analysis is a Book 2 topic.

Mahadasha — life periods ruled by grahas

The most consequential framework that emerges from this list is the Vimshottari Mahadasha (विंशोत्तरी महादशा)— the 120-year cycle in which each graha rules a specific number of years of a person’s life:

The starting graha for an individual is determined by the nakshatra of their natal Moon (the janma nakshatra) — recall the rulership cycle Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury that we mentioned in the nakshatra chapter. The total length of the cycle is 120 years, which is also the maximum natural lifespan in the classical Indian view. We will develop dasha properly in Book 2.

What you should be able to do now

After this chapter, you should be able to:

• Name the nine grahas in order and identify what each is in modern astronomical terms.
• For each graha, recall its rashi rulership, exaltation, debilitation, day, colour, and gem.
• Distinguish natural benefics from natural malefics.
• Explain why Rahu and Ketu are grahas despite not being bodies.
• State the years assigned to each graha in the Vimshottari Mahadasha cycle.
• Read a panchang reference to a graha’s transit and know which rashis the graha is moving between (e.g., “Saturn enters Kumbha”).

Open the daily panchang. The planetary positions are usually shown — each graha’s current rashi, sometimes with degree. Note where each graha is today. Are any of them in their own rashi? In their exaltation? In debilitation? Are any retrograde? These are the daily astronomical facts that your daily panchang is reporting.

From here, the next chapters move from the underlying astronomy and mythology into the practical schedules that a panchang produces — time units, choghadiya, muhurta, and the inauspicious periods like Rahu Kaal. We have laid all the foundation we need.
