The direct answer: What Is Shadbala? Six-Fold Planetary Strength: Shadbala is the six-fold planetary strength score from Swiss Ephemeris and Lahiri. It's a lens on planetary power, not a single life score. AskSoma publishes this at asksoma.ai/blog/what-is-shadbala as a free Vedic astrology resource using Swiss Ephemeris calculations and classical Jyotish interpretation — not generic sun-sign copy.
Shadbala is the six-fold planetary strength score from Swiss Ephemeris and Lahiri. It's a lens on planetary power, not a single life score.
Six ledgers for each planet, not a life-deciding grade.
A Shadbala calculator scores six-fold planetary strength (Shadbala): six ledgers added into one total per planet, usually printed in virupas or rupas. AskSoma computes those ledgers from Swiss Ephemeris and Lahiri (Chitra Paksha) ayanamsa. The total is a screening lens on how a planet sits. It is not a life-deciding score. It cannot stamp a marriage, a job, a visa, or a child's future.
Search boxes do not help. People type "shadbala calculator" because they want to know if Jupiter is strong enough to marry, hire, or emigrate, then they treat a 7.2 rupa line as a verdict. Those are different jobs. Shadbala is six separate ledgers. A total is a convenience. A convenience is not fate.
The six, named once: positional strength (Sthana Bala), directional strength (Dig Bala), temporal strength (Kala Bala), motional strength (Chesta Bala), natural strength (Naisargika Bala), and aspectual strength (Drik Bala). After this paragraph the Sanskrit does not need to be repeated as a brand.
Natural strength is a fixed table. The Sun is always naturally stronger than Saturn in that table, for every birth on earth. Directional strength is not fixed. It needs houses. Houses need a recorded minute and a real city. Adding a fixed table to a house-sensitive table and calling the sum your destiny number is how a lens becomes a scare.
Ashtakavarga at /ashtakavarga-calculator scores houses with bindus. Shadbala scores planets with rupas. Same Swiss Ephemeris stack. Different job. Do not paste a Jupiter rupa onto a tenth-house bindu and call it a career grade.
AskSoma takes planetary longitudes from Swiss Ephemeris, subtracts the Lahiri (Chitra Paksha) ayanamsa, then fills each ledger from that sidereal frame. See /methodology.
Positional strength looks at the sign, and in the schools that use it, at a short list of vargas, including the ninth-part chart at /navamsa-calculator. Exaltation, moolatrikona, own sign, and a friend's sign add. Debilitation subtracts. A tropical app that says Jupiter in Cancer can be sidereal Gemini after Lahiri. The positional line will then disagree with the Co-Star screenshot, and the Co-Star screenshot is the wrong input.
Directional strength awards the four directions: Jupiter and Mercury toward the first house, Sun and Mars toward the tenth, Saturn toward the seventh, Moon and Venus toward the fourth. That is house math. House math is Lagna math. Lagna math is clock math.
Temporal strength listens to day versus night, bright versus dark fortnight, and the hora in the birth city. A Houston clock pasted as IST is a different day-night line and a different hora. Motional strength listens to speed and retrogression; the Sun and Moon use their own motion rules. A few minutes of clock error rarely flip motion. They can flip direction and time.
Aspectual strength adds from benefic aspects and subtracts from malefic ones, on the sidereal longitudes. It is an aspect ledger, not a blessing count. AstroSage and Prokerala also print Shadbala. Compare them on whether they name Swiss Ephemeris, name Lahiri, and show the six ledgers instead of one unexplained grade. AskSoma does that split in the open. It does not claim a higher marriage score.
Open /shadbala-calculator with date, time, and place. The free result should name:
Rahu and Ketu do not hold a classical six-ledger Shadbala in the Parashari scheme this page uses. If a site prints a Rahu rupa total as if it were textbook, ask which later author they borrowed.
Time is not optional here the way it is for a mid-sign Mars. Directional and temporal ledgers need the horizon and the local hour. A silent noon still prints seven tidy totals. Those totals are the sky at 12:00 in whatever city the form defaulted to.
/kundli-calculator draws the natal map: signs, houses, lords, aspects. It answers where the planet sits. Shadbala answers, across six ledgers, how that seat is weighted. You can read a full chart and never add the six. You can add the six and still need the map to know what the planet is doing.
/dasha-calculator seeds the 120-year Vimshottari clock from the Moon's leftover arc. It answers when this planet's period runs. A high Jupiter Shadbala does not start a Jupiter year. A Jupiter Mahadasha start does not raise Jupiter's rupa total. Clock and weight are different instruments.
Families collapse the three because all three print planet names. That is a label collision, not a method. If the visit is show me the chart, stay on /kundli-calculator. If the visit is when does Saturn run, stay on /dasha-calculator. Open this tool when the question is the six-fold weight, and then stop treating the weight as a verdict.
AskSoma computes Shadbala from Swiss Ephemeris with Lahiri ayanamsa. It cannot guarantee a happy marriage, a job, a visa, or a child's future. Treat the result as one input. See /methodology.
A planet above a traditional minimum is not safe. A planet below it is not doomed. The cutoffs themselves vary by school: five rupa for some planets, six or six-and-a-half or seven for others, always in a unit that is sixty virupas to one rupa. A calculator that paints a green tick and sells a stone is doing pastoral work it was not asked to do.
This page will not sell a remedy after scaring you. If a relative sent a screenshot with Saturn is weak, book the puja tonight, read the six ledgers, check the city and the clock, then take the marriage question to /kundli-matching and the period question to /dasha-calculator. No gem, no 24-hour fix, and no urgent-weakness package follows from a virupa.
Shadbala also does not settle immigration, fertility, a court date, or a school admission. Those are legal and medical processes. A strength table is the wrong instrument.
Labeled hypothetical, not a personal reading and not a claimed exact rupa total. Suppose a woman born in Houston on 22 July 1988 at 4:12 a.m. Central Daylight Time. Open /shadbala-calculator with Houston, not with a New Delhi autocomplete. The sidereal signs that feed positional strength will usually hold if the date is right. Directional strength will not. At 4:12 a.m. the rising sign is one Lagna; a silent noon is another. Saturn's directional ledger wants the seventh house. The Sun's wants the tenth. Both of those houses rotate when Lagna rotates. Temporal strength also moves: 4:12 a.m. is a night birth in Houston in July; noon is a day birth. The hora changes.
Now paste the same civil date and 4:12 as if the birth were in Ahmedabad. IST is ten and a half hours ahead of CDT. The sky is a different sky. Motional strength may look familiar. Directional and temporal will not. Natural strength will be identical, because it is a fixed table. Families who argue from the natural line as if it proved the rest are arguing from the one ledger that never heard the hospital clock.
The Jaipur uncle who writes morning on a folder and the Edison cousin who forwards a tropical-app strength screenshot are not answering the same question. The honest output for a missing minute is: positional and natural usable as a rough screen, directional and temporal unknown, total not honest. That sentence is more useful than a confident wrong sum. A cousin actually born that morning in Jaipur, with a local hospital clock, is a third chart. Shared calendar day. Different horizon. Different directional and temporal ledgers.
In Jaipur a match folder sometimes arrives with one circled planet and a word: strong, or weak. The word may have been copied from a tropical app, a guessed noon chart, or an uncle's memory of Guru is high. Recompute the six ledgers on Lahiri first. Then, if the families still want a house filter or a period clock, open those tools with a recorded time.
In Edison and Houston the usual leak is the timezone. Pasting a New Jersey or Texas clock into a form that assumes India flips temporal and directional strength while the natural line stays smugly the same. The other usual leak is a Western planet-strength bar that never named ayanamsa.
Two families can agree on Jupiter's positional strength and still disagree on whether six-and-a-half rupa is enough. That disagreement is about school and about how much weight they give a cutoff. Software can show the six ledgers. It cannot decide the family's rulebook.
Run the live tool at /shadbala-calculator. For the natal map, open /kundli-calculator. For the period clock, open /dasha-calculator.
Shadbala is six-fold planetary strength: positional, directional, temporal, motional, natural, and aspectual ledgers added into one total per planet. AskSoma computes it from Swiss Ephemeris and Lahiri. The total is a lens, not a life score.
No. A rupa total above a traditional minimum is a thicker weight on that planet, not a promotion, a wedding, or a visa. This tool will not say you are safe.
/kundli-calculator draws the natal map: signs, houses, lords. /shadbala-calculator weights each planet across six ledgers. Same birth data. Different job. Do not substitute a strength table for the chart.
/dasha-calculator lists when a planet's Vimshottari period runs. Shadbala does not start or stop a period. A high Saturn weight is not a Saturn year. A Saturn year is not a weight.
Naisargika Bala is a fixed natural table. Dig Bala needs houses, and houses need Lagna. Lagna moves about one sign every two hours. Lose the minute and Dig Bala is a guess.
They print a similar idea. Totals move when ephemeris, ayanamsa, varga list, or cutoff tables differ. Compare disclosures, not a claimed higher grade. AskSoma names Swiss Ephemeris and Lahiri.
No. AskSoma cannot guarantee a happy marriage, a job, a visa, or a child's future. A strength table is the wrong instrument for legal and medical processes.
That disagreement is older than apps. Show both families the six ledgers and the unit. Then they can apply their own minimums. The calculator should not paint a secret pass or fail.
