Ashtamsa (D8) Chart, Longevity [Vedic Parashari]

get_d8_chart

[Vedic Parashari adjunct] D8 divisional chart. NOT one of BPHS's sixteen divisions and found in no classical text searched; the construction is P.V.R. Narasimha Rao (2001), a modern source that says D-8 has different versions: movable signs from Aries, fixed from Sagittarius, dual from Leo. The rule this tool used before 2026-09-27 (even signs from the 5th, no source) rides beside it in 'alternativeReadings'; each block carries 'reading' and 'readingSource', and 'notInBphsSixteen' is true. Each natal sign divided into 8 parts of 3.75°, longevity, sudden events. Returns D8 ascendant, placements, 8th-house readout. Companion to get_longevity_balarishta.

Birth data

This tool requires birth data on every call. The MCP server is stateless, so calling set_birth_profile first validates the data and returns the reading plan, but it does not store anything. Repeat the same five fields here.
