The Navagrahas

Nava means nine. Graha means seizer — not planet in the modern astronomical sense, but an entity that grips or influences. The navagrahas are the nine bodies through which Jyotish reads a chart: seven classical planets and two mathematical points derived from the Moon's orbit.

The Seven Classical Grahas§

	Graha	Rules	Significations
☉	Sun Surya	♌ Leo	Soul, authority, father, government. Burns what it contacts too closely.
☽	Moon Chandra	♋ Cancer	Mind, emotion, mother, nourishment. Waxing = benefic; waning = malefic. Changes sign every ~2.5 days.
♂	Mars Mangala	♈ Aries ♏ Scorpio	Energy, courage, siblings, fire, surgery. Natural malefic. Special aspects: 4th, 7th, 8th.
☿	Mercury Budha	♍ Virgo ♊ Gemini	Intellect, speech, commerce, mathematics. Neutral — takes the colour of its companions. Never more than 28° from the Sun.
♃	Jupiter Guru	♐ Sagittarius ♓ Pisces	Wisdom, dharma, children, teachers, expansion. The great benefic. Special aspects: 5th, 7th, 9th. ~12 year cycle.
♀	Venus Shukra	♎ Libra ♉ Taurus	Desire, beauty, relationships, luxury, arts. The other great benefic. Never more than 48° from the Sun.
♄	Saturn Shani	♒ Aquarius ♑ Capricorn	Discipline, delay, longevity, karma, limitation. Natural malefic. Special aspects: 3rd, 7th, 10th. ~29.5 year cycle.

The Two Lunar Nodes§

Rahu and Ketu are not physical bodies — they are the two points where the Moon's orbit crosses the ecliptic. They are always exactly 180° apart and always in retrograde motion.

☊	Rahu North Node	Amplifies and obsesses. Worldly desire, ambition, foreignness, unconventional paths. Acts like Saturn, sometimes Jupiter.
☋	Ketu South Node	Separates and dissolves. Spirituality, liberation, past-life patterns. The headless body — acts without intellect. Acts like Mars.

Natural Benefics and Malefics§

The navagrahas divide into two camps by default nature:

Natural benefics — ♃ Jupiter · ♀ Venus · ☽ Moon (waxing) · ☿ Mercury (alone)

Natural malefics — ♄ Saturn · ♂ Mars · ☉ Sun · ☽ Moon (waning) · ☊ Rahu · ☋ Ketu

This classification is just a baseline. A planet's functional role in a specific chart — determined by which houses it rules for a given lagna — can override it entirely. Saturn becomes a yogakaraka for Taurus and Libra lagnas. Jupiter can become a functional malefic for Capricorn and Aquarius lagnas. The natural nature is a default; functional nature is chart-specific. Planetary loyalties covers the natural friendship relationships between grahas in full.

Nine grahas, one chart, infinite combinations. Each graha contributes a distinct quality and governs specific domains of life. Understanding the navagrahas — their natural temperament, the signs they rule, and the houses they occupy in a given chart — is the foundation everything else in Jyotish is built on. Cast your chart to see where each graha falls in your sky.
