The four schemes

Which charts each scheme counts, and how the twenty points are shared between them. Every weight row sums to exactly 20.

Vimsopaka Bala is the classical answer to a question the rasi chart cannot settle on its own: does a planet keep its dignity when you look at it through the divisional charts? The name means of twenty parts, and the answer is always a number between 0 and 20 — one score per scheme of vargas, computed here by the same engine that draws the charts.

What Vimsopaka Bala measures

This is a dignity census, not a strength calculation in the physical sense. Shad Bala adds six measurable quantities — positional, directional, temporal, motional, natural and aspectual strength — and reports a number in the hundreds of shashtiamsas. Vimsopaka adds none of them. It walks through a named group of divisional charts, asks in each one whether the planet has landed in a sign it owns or is exalted in, and converts the tally into a score out of twenty.

That narrowness is the point. A planet can be exalted in the rasi chart and score badly here, because exaltation in D-1 says nothing about where the planet falls in the navamsa, the dwadasamsa or the shashtiamsa. The vargas are where the detail of a life is read, and Vimsopaka Bala is the single figure that says whether a planet holds up when the chart is divided.

How the twenty points are shared out

Each varga in the scheme is given a fixed share of the twenty points, and the planet keeps its share in proportion to the dignity it holds in that chart. Add the kept shares and you have the score. Four schemes are in use because different authorities count a different number of charts, and every one of them is normalised to the same twenty points — which is what makes the four scores comparable across a single row.

The weights are worth reading closely. In the six-chart Shadvarga scheme the rasi chart alone carries six of the twenty points, so a planet dignified in D-1 starts a long way ahead. In the ten- and sixteen-chart schemes the rasi chart drops to three or three and a half, and the shashtiamsa — D-60, the finest classical division — takes the largest single share. Sum any column and you get exactly twenty; that check is the quickest way to tell whether a table of weights has been transcribed correctly.

Reading the amsa name next to the score

Each cell carries a name as well as a number — Chaamaraamsa, Simhaasanaamsa, Poornachandraamsa — and the name is not the score. It is the vaiseshikamsa grade: a plain count of how many charts in the scheme place the planet in a sign it owns or is exalted in. Count the charts listed in the cell and you have the grade number. In the worked example Saturn's sixteen-chart cell lists nine charts, its vaiseshikamsa score is nine, and nine is what earns the name Poornachandraamsa.

Each scheme has its own ladder of names for the same counts, which is why a planet's amsa changes across the row while its dignity has not moved at all. A count of four is Chaamara in the six-chart scheme, Gopura in the ten-chart scheme and Nagapurushaamsa in the sixteen. Below a count of two no name is awarded, and the engine prints No Amsa — which is not an error and does not mean the score is zero.

What a high or low score means

By convention a score of fifteen or more is read as strong, ten to fifteen as workable, and below ten as a planet that cannot be relied on to deliver the matters it signifies without support. Those bands are conventional rather than scriptural, and they are far less informative than reading the whole row at once.

The useful signal is the shape across the four schemes. A planet that scores well on six charts and collapses on sixteen is dignified in the coarse divisions and not in the fine ones — it looks better in a quick reading than it behaves over time. In the worked example Saturn holds between 17.5 and 18.9 in all four schemes while Rahu never clears 7.5, and that gap is far more useful than either number alone.

One limit is worth stating plainly. Vimsopaka Bala measures dignity across charts and nothing else. It knows nothing about which house the planet occupies, what aspects it, or when its dasha runs. A planet scoring eighteen out of twenty in the sixth house is still a planet in the sixth house.
