Graha (Planet) in Vedic Astrology: The 9 Navagraha
Graha literally means "that which seizes" — reflecting the Vedic view that celestial bodies exert a tangible influence on human life. Vedic astrology works with nine Grahas (Navagraha): the Sun (Surya), Moon (Chandra), Mars (Mangal), Mercury (Budha), Jupiter (Guru), Venus (Shukra), Saturn (Shani), and the two lunar nodes — Rahu (North Node) and Ketu (South Node).
Natural Benefics and Malefics
Jupiter, Venus, and the waxing Moon are natural benefics — their influence tends toward growth and harmony. Sun, Mars, Saturn, Rahu, Ketu, and the waning Moon are natural malefics — they bring challenges, discipline, and transformation. However, a planet's functional nature depends on which houses it rules for the specific Ascendant.
Planetary Significations
Each Graha governs specific life themes: Sun rules authority and father; Moon governs mind and mother; Mars controls energy and siblings; Mercury rules intellect and communication; Jupiter signifies wisdom and fortune; Venus governs relationships and luxury; Saturn represents discipline and longevity; Rahu drives worldly ambition and obsession; Ketu brings spirituality and detachment.
Planetary Strength
A Graha's effectiveness depends on its dignity — whether it is in exaltation, own sign, friendly sign, debilitation, or is combust or retrograde. The Shadbala system quantifies six types of strength, giving a precise measure of each planet's power in the Kundli.
Grahas and Timing
Each Graha rules a specific Mahadasha period and a set of Nakshatras. During its Dasha, a planet's themes dominate. Its transit through different signs triggers shorter-term events. Remedies targeting specific Grahas — gemstones, mantras, and rituals — are prescribed to strengthen weak or afflicted planets.
