Astro Vastu ( Part 2 )

In Vedic astrology (Jyotish), the Sun, Moon, Rahu, and Ketu are four of the nine celestial influences, collectively called the Navagrahas. Here’s a summary of each:

Sun (Surya)

• Type: Star, considered a planet in astrology

• Represents: Soul (Atma), ego, authority, father, vitality, leadership

• Zodiac Sign: Rules Leo (Simha)

• Day: Sunday

• Element: Fire

• Nature: Malefic (but gives beneficial results when well placed)

Moon (Chandra)

• Type: Natural satellite of Earth, considered a planet in astrology

• Represents: Mind, emotions, mother, mental stability, intuition, nurturing

• Zodiac Sign: Rules Cancer (Karka)

• Day: Monday

• Element: Water

• Nature: Benefic (gives emotional sensitivity and receptiveness)

Rahu

• Type: Shadow planet (Chhaya Graha), north lunar node

• Represents: Obsession, illusion, desires, foreign things, innovation, confusion, rebellion

• Zodiac Sign: Has no sign of rulership, but does well in Taurus and Gemini

• Day: Saturday or Wednesday (varies)

• Element: Air-like (illusionary)

• Nature: Malefic (causes worldly obsession, but can give success in material pursuits)

Ketu

• Type: Shadow planet, south lunar node (opposite Rahu)

• Zodiac Sign: No sign of rulership, but does well in Scorpio and Sagittarius

• Day: Tuesday or Thursday (varies)

• Element: Ether-like (detached)

• Nature: Malefic (causes loss, but promotes spiritual growth)

Key Points about Rahu and Ketu:

• They are not physical planets; they're mathematical points where the Moon’s orbit crosses the ecliptic (the apparent path of the Sun).

• They are always exactly 180° apart and move in a retrograde motion (opposite to the planets).

In astrology, planets represent different aspects of personality, life events, and energies. Each planet rules specific signs, has certain qualities (benefic or malefic), and governs key areas of life.
