It is a +non-redistributable method source, not a licensed replacement for a published +critical edition. This audit records page labels and derived verification scope, +not book text or page images. + +## Shadbala + +| Local page label | Verifiable content | Permitted use | +| --- | --- | --- | +| 66 | Six components: Sthana, Dik, Kala, Chesta, Naisargika, Drik; seven classical planets only; 60 Virupa = 1 Rupa. | Component schema and unit contract. | +| 66–71 | Subcomponent grouping and Dik Bala calculation convention. | Method-variant attribution. | +| 72 | Planet-specific total and component Virupa strength thresholds. | Threshold provenance only. | + +The pages contain formula/threshold material, but no single native chart with +birth input and all six computed component values.

They can isolate an allocation-table disagreement but do not make +one engine the numeric truth oracle. + +## Related local sources + +- B.V. Raman, *How to Judge a Horoscope*, Vols. 1–2: many numbered natal + examples with birth data and Dasha balances; the inspected Vol. 2 index + defines Shadbalas but does not provide a component worked table. +- K.N.
