Shadbala (Six-Fold Strength)

Shadbala aggregates six distinct strengths for every planet: Sthana Bala (positional strength from sign and varga placements), Dig Bala (directional strength by house — Sun strongest on the 10th, Moon on the 4th, Jupiter/Mercury on the 1st, Saturn on the 7th), Kala Bala (temporal strength — day/night sect, waxing/waning Moon, year/month/day/hour lords), Cheshta Bala (motional strength from retrogression and speed relative to mean motion), Naisargika Bala (inherent strength of each graha — Sun strongest by nature, Saturn weakest), and Drik Bala (aspectual strength from benefic and malefic aspects received). Each component is measured in Rupas and totalled. Parashara's minimum Rupa thresholds (e.g., Sun ≥ 6.5, Moon ≥ 6.0, Mars ≥ 5.0) determine whether a planet has enough strength to actually deliver its natal indications — a key distinction professional Jyotishis make between a well-placed planet and an effective one.

A well-placed planet that fails Shadbala cannot fully deliver on its promise; a modestly placed planet with strong Shadbala often outperforms it. Shadbala tells you which planets to actually rely on for real-world results — not just which ones look good on paper.
