Shadbala: Measuring a Planet's Power to Deliver
The six sources of strength, the units that quantify them, and the thresholds that separate a planet that promises from one that performs
Dignity tells you whether a planet is comfortable; strength tells you whether it can act. A planet may sit exalted and still fail to deliver, while a modestly placed planet quietly runs the chart. Shadbala — the "six strengths" — is Parashara's system for turning this intuition into a number, scoring every planet across six independent sources of power and setting a bar each must clear to be called strong. It is computationally heavy and almost always left to software, but no advanced reader should use the output without understanding what the six components mean and where the thresholds come from.
Strength is capacity, not benevolence
Before anything else, fix the distinction that beginners miss: Shadbala measures capacity to deliver, not the quality of what is delivered. A strong benefic delivers good strongly; a strong malefic delivers difficulty strongly. Strength amplifies whatever a planet is set to do by its dignity, lordship, and placement. Read Shadbala alongside those factors, never in place of them.
Strength is expressed in Rupas and Virupas, where 1 Rupa = 60 Virupas (shashtiamsas). Each of the six sources is computed in virupas, summed, and divided by sixty to give a planet's total in rupas — the figure you compare against its requirement.
The six sources
| Bala | Meaning | What it measures |
|---|---|---|
| Sthana Bala | Positional | Exaltation proximity, dignity across the vargas, odd/even placement, and house type (kendra/panapara/apoklima) |
| Dig Bala | Directional | Strength from occupying the planet’s ideal direction (house) |
| Kala Bala | Temporal | Strength from time — day/night, lunar fortnight, year/month/day/hour rulership, solstice, and planetary war |
| Cheshta Bala | Motional | Strength from the planet’s speed and state of motion, chiefly retrogression |
| Naisargika Bala | Natural | A fixed, inherent hierarchy of brightness independent of the chart |
| Drik Bala | Aspectual | Net benefic minus malefic aspects falling on the planet |
Inside the components
Sthana Bala — positional strength
The largest and most composite source. It combines Uccha Bala (proximity to the exaltation point, full at exact exaltation and zero at debilitation), Saptavargaja Bala (dignity summed across seven divisional charts), Ojhayugmarasyamsa Bala (male planets — Sun, Mars, Jupiter — gaining in odd signs and navamshas; female planets — Moon, Venus — in even), Kendradi Bala (60 virupas in a kendra, 30 in a panapara, 15 in an apoklima), and Drekkana Bala (male planets strong in the first drekkana, and so on).
Dig Bala — directional strength
Each planet has a home direction where it is fully empowered and the opposite house where it is powerless. Jupiter and Mercury peak in the East (the Ascendant), the Sun and Mars in the South (the 10th), Saturn in the West (the 7th), and the Moon and Venus in the North (the 4th). Strength scales smoothly from 60 virupas at the ideal cusp down to zero at the opposite.
Kala Bala — temporal strength
A cluster of time-based measures: Nathonnata (Moon, Mars, Saturn gain at night; Sun, Jupiter, Venus by day; Mercury always), Paksha (benefics strengthen as the Moon waxes, malefics as it wanes), Tribhaga, the lords of the year, month, day, and hour, Ayana Bala from declination, and Yuddha Bala from planetary war.
Cheshta Bala — motional strength
Strength from the planet's state of motion. A retrograde planet earns high Cheshta Bala — one reason retrogression intensifies a planet rather than simply weakening it. The Sun and Moon never retrograde, so the Sun's Cheshta is taken from its Ayana Bala and the Moon's from its Paksha Bala.
Naisargika Bala — natural strength
A fixed ladder of inherent brightness, the same in every chart, in steps of 60/7 virupas: Sun 60.00, Moon 51.43, Venus 42.86, Jupiter 34.29, Mercury 25.71, Mars 17.14, Saturn 8.57. It is why the Sun always brings a baseline of force and Saturn always works slowly.
Drik Bala — aspectual strength
The net effect of aspects on the planet: benefic aspects add, malefic aspects subtract, weighted by the strength of the aspect. A planet drowning in malefic aspects loses Drik Bala even if strong elsewhere.
The thresholds that matter
A total Shadbala figure is meaningless until compared with the minimum required for that planet. Each planet has its own bar; clearing it marks the planet as strong enough to deliver its promises.
| Planet | Required Shadbala (Rupas) |
|---|---|
| Sun | 6.5 |
| Moon | 6.0 |
| Mars | 5.0 |
| Mercury | 7.0 |
| Jupiter | 6.5 |
| Venus | 5.5 |
| Saturn | 5.0 |
Mercury needs the most and Saturn and Mars the least — which is why a Mercury just over its high bar is genuinely powerful, while a Saturn only a little above five rupas is comfortably strong. Ranking planets by how far they exceed their own requirement, rather than by raw total, gives the truest picture of which planet dominates a chart.
Practitioner’s note. Related figures fall out of the same computation: Ishta Phala and Kashta Phala (the good and bad yield of a planet, derived mainly from Uccha and Cheshta Bala) and Bhava Bala (the strength of each house). Together they let you grade not just planets but the houses they govern.
Applying it in practice
Grade the dasha lord. A dasha run by a planet far below its required strength underdelivers even when the planet is well placed by sign.
Test a yoga-forming planet. A Raja Yoga rests on the strength of the planets that form it; Shadbala tells you whether they can carry it.
Compare rival significators. When two planets could produce the same result, the stronger by Shadbala usually prevails.
Choose the emphasis for guidance. The strongest, best-placed planet is the natural focus for constructive counsel and for remedial emphasis.
Common mistakes
Reading strength as goodness — a strong malefic afflicts strongly, it does not turn benign.
Comparing raw totals across planets instead of comparing each planet against its own requirement.
Trusting a Shadbala figure without an accurate birth time — several components depend on precise time of day.
Treating Shadbala as the whole verdict; it grades capacity, while dignity, lordship, and placement decide direction.
Ignoring which component supplies the strength — a planet strong only in Naisargika Bala is far less impressive than one strong in Sthana and Dig Bala.
Used well, Shadbala answers the question dignity cannot: not "is this planet comfortable?" but "can it actually act?" — and that is the question on which most real predictions turn.
