Planetary Strength (Shadbala)
A planet's effect is determined by its Shadbala (六種力量) — a comprehensive six-fold scoring system measured in Virupas:
- Sthana Bala: Positional strength (Exaltation, Dignity).
- Dig Bala: Directional strength (Sun in 10th, Moon in 4th).
- Kala Bala: Temporal strength (Day/Night birth, Solar position).
- Cheshta Bala: Motional strength (Retrograde vs. Direct speed).
- Naisargika Bala: Natural brightness (Sun is naturally strongest).
- Drik Bala: Aspectual strength (Support vs. Affliction from other planets).
The Yoga (Combination) System
Yogas (格局) are specific planetary combinations that produce extraordinary results. Notable types include:
- Pancha Mahapurusha Yogas: Five planets in their own or exalted signs in Kendra houses, indicating a 'Great Person' archetype.
- Dhana Yogas: Wealth combinations between the 1st, 2nd, 5th, 9th, and 11th house lords.
- Raja Yogas: Power combinations between Kendra (Action) and Trikona (Luck) lords.
- Neecha Bhanga Raja Yoga: A 'cancelled' debilitation that turns weakness into massive success.
