Methodology and astrological context for Graha Gunak.
Computes the Graha Gunak (planet multiplier) values for a person's Vedic birth chart — a classical Ashtakavarga technique that derives a weighted strength index for each of the seven classical planets by multiplying the planet's fully reduced Bhinnashtakavarga score in its occupied house by the number of bindus contributed to that house, producing a planet-level composite index used for individual planetary strength assessment.
Graha Gunak is the planet-centric counterpart to Rasi Gunak. While Rasi Gunak evaluates the composite strength of each sign by weighting house scores against planetary occupancy, Graha Gunak focuses on the individual planets themselves — assessing how strongly each planet is placed within the Ashtakavarga framework by combining its own reduced Bhinnashtakavarga score in its natal house with the aggregate strength of that house from the Sarvashtakavarga.
In classical Vedic Ashtakavarga methodology, the Graha Gunak for a planet is derived by multiplying the planet's own reduced bindu score in the house it occupies by the fully reduced Sarvashtakavarga score of that same house. This product yields a composite index that captures both the planet's intrinsic Ashtakavarga strength and the overall environmental strength of the house it inhabits. A planet with a high Graha Gunak is considered well-placed and powerfully supported by the Ashtakavarga framework; a planet with a low Graha Gunak is considered weakly positioned regardless of other chart factors.
This endpoint computes the full birth chart from the provided date, time, and geographic coordinates, applies the complete Ashtakavarga reduction pipeline (Trikon Shodhan followed by Ekadhipatya Shodhan), and then calculates the Graha Gunak for each of the seven classical planets. The result is a planet-wise composite strength index ready for use in planetary strength analysis, dasha evaluation, and predictive astrology.
