Vimsopaka bala is a planet's report card across the divisional charts, marked out of twenty
Vimsopaka bala is a planet's report card across the divisional charts, marked out of twenty. The birth chart shows where a planet stands; the divisional charts show how it holds up when life is examined domain by domain — marriage in one chart, career in another, the deep karmic grain in the subtlest. A planet can look splendid in the rashi chart and quietly fall apart as the divisions are opened, or look ordinary on the surface while standing in dignity after dignity underneath. Vimsopaka bala turns that scattered picture into a single number: each of ten divisional charts contributes a weighted share of twenty points, the planet earning its share where it stands well and losing it where it stands in an enemy's house. The weighting is deliberate — the rashi chart counts for much, and the shashtiamsa, the sixty-fold division said to carry the karmic residue of past lives, counts for the most. A planet scoring high has depth: its promises survive scrutiny, and its periods tend to deliver. A low scorer is thin ice — attractive on the surface, unreliable under weight. Astrologers reach for it when judging whether a dasha lord can actually pay what the birth chart appears to promise.
Parashara assigns twenty points across the dashavarga: three for the rashi chart, five for the shashtiamsa, and one and a half for each of the remaining eight divisions — the planet earning full points in own or exaltation vargas and graded shares by its relationship with each varga's lord. Scores are ranked from purna (full) downward, the higher the total the more capable the graha.

The engine scores the BPHS dashavarga scheme: D1 weighted 3, D60 weighted 5, and D2, D3, D7, D9, D10, D12, D16 and D30 at 1.5 each. In each division a planet in its own or exaltation sign takes the full weight; otherwise the compound (natural + temporary) relationship with the division's sign lord grades the share. Fifteen or more reads as excellent, ten to fifteen sound, below ten a planet needing support. The graha bala tool shows it beside the related Dwadasa Vargeeya Bala — one point for each of the twelve vargas D1 to D12 where the planet stands in own, exaltation or a friend's sign; seven or more marks strength that holds across the divisions.
