Components of Shadbala

The six types of strength in Shadbala are:

1. Sthanabala (Positional Strength):
   • This measures the strength of a planet based on its position in the zodiac or in specific houses.
   • Key factors:
     • Exaltation/Debilitation: A planet in its exaltation sign is very strong, while in debilitation, it is weak.
     • Own Sign: A planet in its own sign or Moolatrikona gains strength.
     • Directional Strength (Digbala): Some planets are stronger in specific directions (e.g., Jupiter and Mercury in the 1st house, Mars in the 10th house).
2. Digbala (Directional Strength):
   • This measures the strength of a planet based on its placement in one of the four quadrants (kendras: 1st, 4th, 7th, 10th houses).
   • Key positions:
     • 1st House (East): Strong for Jupiter and Mercury.
     • 4th House (North): Strong for the Moon and Venus.
     • 7th House (West): Strong for Saturn.
     • 10th House (South): Strong for the Sun and Mars.
3. Kalabala (Temporal Strength):
   • This measures a planet’s strength based on time-related factors such as:
     • Day or Night Strength: Some planets are stronger during the day (e.g., the Sun, Jupiter), while others are stronger at night (e.g., the Moon, Saturn).
     • Varsha, Masa, Vara, Hora: Strength related to the year, month, weekday, and hour of birth.
4. Cheshtabala (Motional Strength):
   • This measures a planet’s strength based on its speed and motion.
   • Planets in retrograde motion gain extra strength, while those in combustion (close to the Sun) lose strength.
5. Naisargika Bala (Intrinsic or Natural Strength):
   • This measures the inherent strength of planets based on their natural influence.
   • Order of strength (from strongest to weakest):
     • Sun > Moon > Venus > Jupiter > Mercury > Mars > Saturn.
6. Drikbala (Aspect Strength):
   • This measures the strength a planet gains from receiving benefic or malefic aspects from other planets.
   • Benefic aspects (from Jupiter, Venus, etc.) add strength, while malefic aspects (from Saturn, Rahu, etc.) reduce strength.

Calculation of Shadbala

Shadbala is calculated as a composite score from the above six components. It is expressed in units called Rupa or Shashtiamsha (1/60th parts):

• 1 Rupa = 60 Shashtiamsha.
• A planet is considered strong if it has at least 6 Rupa (360 Shashtiamsha) or more in Shadbala.

Significance of Shadbala

1. Planetary Strength Assessment:
   • Planets with higher Shadbala scores are better equipped to deliver their promised results in a horoscope.
   • Planets with lower Shadbala scores may struggle to manifest their effects or may need remedies.
2. Prioritizing Remedies:
   • Weak planets (low Shadbala) may require strengthening through gemstones, mantras, or rituals.
3. Timing of Events:
   • Shadbala helps in determining the periods (dashas, transits) when a planet will give strong or weak results.
4. House Strength:
   • A planet’s Shadbala also influences the strength of the house it rules.

Shadbala and Functional Nature of Planets

• Benefic Planets: If strong, they provide support, positivity, and favorable results in their respective areas.
• Malefic Planets: If strong, they may deliver challenges more intensely but also have the capacity to bestow rewards if functionally benefic in the chart.

Conclusion

Shadbala is a comprehensive system in Vedic astrology for evaluating planetary strength, incorporating positional, directional, temporal, and other factors. It provides astrologers with a detailed understanding of how each planet will function in a native’s life and helps in offering accurate predictions and remedies.
