What the Chart Counts
How often a horoscope truly signals a broken marriage or the absence of children, measured across both the strengths and the afflictions, in the birth chart and in the divisional charts.
Every marriage carries friction, and every chart shows some affliction to the house of partnership. That is not a prophecy. It is the background hum of planets spread across a wheel. The honest question is never whether a chart shows a problem, because it almost always does, but how many problems converge, how deep they run across the divisional charts, and how rare that convergence really is. This study answers with counting rather than fear, and it gives equal weight to the blessings, because a chart that protects a marriage matters as much as one that strains it.
The rules are drawn from Brihat Parashara Hora Shastra and the Bhrigu Sutram, paraphrased and cited by name. Each was tested across twenty thousand simulated charts from a real Swiss Ephemeris over a sixty year birth window, read with Lahiri ayanamsa and equal bhava, and judged in three layers: the birth chart, the Navamsa for marriage, and the Saptamsa for children.
The Funnel of Confirmation
Read the same chart through wider demands and watch the population fall away. In my practice the deciding layer is the Navamsa, where I weigh the first slot and the seventh slot above all. The birth chart raises the suspicion. The Navamsa confirms or dissolves it.
Against the real world: research places marital distress at roughly 20 to 34 percent of couples, matching the four-or-more tier. India’s recorded divorce rate is near 1 percent, the lowest in the world, which the fully confirmed tier approaches. The chart reads the pressure. Society decides how much becomes a filing.
What to Check for a Failing Marriage
In my practice the 7th lord’s link to the 12th (separation, loss, the bed) and the 6th (conflict, litigation) outweighs the planet merely sitting in the 7th. The Navamsa is read at its first and seventh slots, both house and lord. The Venus doshas below apply chiefly to a male native, where Venus is the wife karaka.
| Condition to check | Layer | Source | How often | Weight |
|---|---|---|---|---|
| 7th lord in, or joined to the lord of, the 12th | D1 | BPHS, 7th house | 16.4% | Primary |
| 7th lord in, or joined to the lord of, the 6th | D1 | BPHS, 7th house | 21.5% | Primary |
| 7th lord in, or joined to the lord of, the 8th | D1 | BPHS, 7th house | 21.1% | High |
| 7th lord in fall, combust, or an enemy sign | D1 | BPHS ch. 80 | 22.5% | High |
| Sun, Mars, Saturn or Rahu in the 7th (no dignity exception) | D1 | Bhrigu Sutram | 28.8% | High |
| Ketu in the 7th | D1 | Bhrigu Sutram | 8.2% | Support |
| A debilitated planet sitting in the 7th | D1 | BPHS, 7th house | 4.5% | High |
| Venus with Saturn (karaka chilled, male native) | Karaka | Classical kalatra | 8.4% | High |
| Venus with Ketu (karaka severed) | Karaka | Classical kalatra | 8.0% | High |
| Venus with the Sun, or Venus combust (karaka burnt) | Karaka | Combustion doctrine | 23.3% | Support |
| Jupiter afflicted (husband karaka, female native) | Karaka | Karaka doctrine | 48.1% | Support |
| Malefic or node in the 7th slot of the Navamsa | D9 | D9 spouse doctrine | 35.6% | High |
| Lord of the Navamsa 7th debilitated or in its dusthana | D9 | D9 spouse doctrine | 32.8% | High |
| Malefic or node in the 1st slot of the Navamsa | D9 | D9 lagna doctrine | 35.4% | Support |
| Lord of the Navamsa lagna debilitated or in its dusthana | D9 | D9 lagna doctrine | 32.5% | Support |
| A debilitated planet in the 2nd from Upapada | Upapada | BPHS ch. 30 | 4.6% | Primary |
| Saturn with Rahu in the 2nd from Upapada | Upapada | BPHS ch. 30 | 0.8% | Primary |
| A malefic in the 2nd from Upapada | Upapada | BPHS ch. 30 | 33.6% | High |
Primary conditions are rare and decisive. High conditions matter once stacked. Support conditions are too common to mean much alone.
What Protects and Promises a Good Marriage
The same chart that worries you may carry its own cure. These are the configurations that steady a marriage, and they are common enough that fear is rarely warranted. A single strong protector can outweigh several afflictions.
| Strength to look for | Layer | Source | How often | Weight |
|---|---|---|---|---|
| 7th lord in its own or exaltation sign | D1 | BPHS ch. 80 | 23.7% | Strong |
| A benefic in the 7th, or a clean, empty 7th | D1 | Bhrigu Sutram | 71.1% | Strong |
| Venus dignified, not combust, free of Saturn, Sun and Ketu | Karaka | Karaka doctrine | 18.0% | Strong |
| A benefic in, or aspecting, the Upapada | Upapada | BPHS ch. 30 | 21.5% | Protective |
| Navamsa 7th lord dignified, or a benefic in the D9 7th slot | D9 | D9 spouse doctrine | 32.9% | Protective |
The classical overrides hold above all: the 7th lord or Venus in its own sign, or the 2nd-from-Upapada lord in its own sign, pushes any loss to advanced age.
The Same Logic, the House of Progeny
The method transfers cleanly. The significator is Jupiter, the house is the 5th, the maraka is the 6th (the 2nd from the 5th), and the deciding divisional is the Saptamsa, where I weigh the first slot and the fifth slot.
Against the real world: the World Health Organization places lifetime infertility near 12 to 17.5 percent, India around 8 to 12 percent of couples, and miscarriage near 13 percent of recognized pregnancies. The four-or-more tier sits inside the infertility band, and the strict, Saptamsa confirmed signature reaches the floor of genuine involuntary childlessness.
What to Check for Denied or Delayed Children
| Condition to check | Layer | Source | How often | Weight |
|---|---|---|---|---|
| 5th lord in the 6th, 8th or 12th, enemy sign, or fall | D1 | BPHS ch. 16 | 24.4% | Primary |
| 5th lord in the 6th (maraka for progeny) | D1 | BPHS ch. 24 | 7.7% | High |
| Two of Mercury, Ketu, Saturn in the 5th (Kakavandhya) | D1 | BPHS ch. 16 | 2.0% | Primary |
| A debilitated planet in the 5th | D1 | BPHS, 5th house | 4.9% | High |
| Sarpa shaapa: Sun or 5th lord with Rahu or Ketu | D1 | Bhrigu Sutram | 18.1% | High |
| Rahu or Ketu in the 5th | D1 | Bhrigu Sutram | 16.7% | High |
| A malefic in the 5th | D1 | Bhrigu Sutram | 35.4% | Support |
| Jupiter, the putra karaka, afflicted | Karaka | Karaka doctrine | 48.1% | Support |
| Malefic or node in the 5th slot of the Saptamsa | D7 | D7 progeny doctrine | 35.8% | High |
| Lord of the Saptamsa 5th debilitated or in its dusthana | D7 | D7 progeny doctrine | 31.3% | High |
| Malefic or node in the 1st slot of the Saptamsa | D7 | D7 lagna doctrine | 35.5% | Support |
| Lord of the Saptamsa lagna debilitated or in its dusthana | D7 | D7 lagna doctrine | 32.8% | Support |
What Promises Children
The texts are as generous with progeny yogas as they are stern with the afflictions, and these promises are common. The presence of even one strong protector reframes a worried fifth house.
| Strength to look for | Layer | Source | How often | Weight |
|---|---|---|---|---|
| 5th lord exalted, in own sign, or in the 2nd, 5th or 9th | D1 | BPHS ch. 16, v. 16 | 53.7% | Strong |
| 5th lord joined or aspected by Jupiter, Venus or Mercury | D1 | BPHS ch. 16, v. 12 | 60.8% | Strong |
| Jupiter dignified and unafflicted | Karaka | Karaka doctrine | 14.6% | Strong |
| A benefic in the 5th | D1 | BPHS, 5th house | 21.3% | Protective |
| Saptamsa 5th lord dignified, or a benefic in the D7 5th slot | D7 | D7 progeny doctrine | 32.1% | Protective |
How the Counting Was Done
Every figure here is a Monte Carlo estimate, offered as research and illustration, never as deterministic prediction. A number you can audit is worth more than a tradition you must take on faith.
The engine
- Twenty thousand charts. Each cast from a real Swiss Ephemeris, not a uniform random model, so the true clustering of planets is preserved.
- Birth window 1955 to 2015. A full sixty years, so the slow movers, Saturn, Rahu and Ketu, sample evenly across all twelve ascendants. A shorter window cannot, and would distort any per-ascendant claim.
- Random Indian births. Latitude 8 to 32 north, longitude 70 to 90 east, random clock time, giving a realistic spread of ascendants.
- Lahiri ayanamsa, equal bhava, lagna only. The house of a body is counted from the rising sign, in keeping with the doctrine I follow.
- Three layers judged. The birth chart (D1), the Navamsa (D9) read at its first and seventh slots for marriage, and the Saptamsa (D7) read at its first and fifth slots for children, each tested by both house tenancy and the lord’s condition.
What counts as an affliction
- Placement in a dusthana, the 6th, 8th or 12th.
- Debilitation, the sign of greatest weakness, in the birth chart or in the divisional.
- Combustion, within the classical orb of the Sun, applied to the karakas.
- Conjunction with the lord of a 6th, 8th or 12th, mixing conflict, crisis or loss into the matter at hand.
- A natural malefic or a node tenanting the house, counted with no dignity exception for the 7th, in keeping with the combined Parashari and Bhrigu reading.
The probability logic
- Independent conditions multiply. For two near-independent afflictions, the chance of both is the product, never the sum. Adding would badly overcount, the common error of fear astrology.
- Mutually exclusive outcomes add. Where two results cannot co-occur, their probabilities sum.
- Stacks are measured, not formulated. Because real afflictions are correlated, the convergence figures are counted directly across the twenty thousand charts rather than derived by formula.
- Raw before cancellation. A condition is counted whenever its geometry occurs, before classical cancellations. This is why the single-factor rates run high and only the stacked, divisionally confirmed tiers carry diagnostic weight.
Master Summary
Every tier, side by side with the real outcome it maps to. Read top to bottom as a descent from meaningless noise to genuine, rare signal.
| Tier | Astrological frequency | Real-world anchor |
|---|---|---|
| Marriage · at least one affliction | 97% | Universal friction. Maps to nothing. |
| Marriage · four or more stacked | 28.5% | Marital distress, 20 to 34 percent. |
| Marriage · separation signature (D1) | 11.8% | Urban distress and separation pressure. |
| Marriage · confirmed in Navamsa | 9.5% | Serious, rupture-prone unions. |
| Marriage · Navamsa and Upapada confirmed | 2.4% | Approaches India’s 1 percent divorce floor. |
| Children · four or more stacked | 16.7% | Infertility band, 12 to 17.5 percent. |
| Children · denial signature confirmed in Saptamsa | 3.8% | Severe progeny difficulty. |
| Children · strict signature, all layers | 2.0% | Floor of involuntary childlessness. |
