get_rasi_dashas

Parashari, not KP. The ten sign-based dashas Brihat Parashara Hora Shastra gives in ch. 46, each period carrying its verses: Chara in the text's own reading (direction from the 9th house's pada, v. 167; years counted from a rasi to its lord, onwards from a vishama-pada rasi and in reverse from a sama-pada one, the dual-lorded rasis to the stronger lord by the vv. 158-166 ladder, +1 or -1 for an exalted or debilitated planet in the counted-to rasi); Sthira from the Brahma graha's rasi at 7, 8, 9 years by class (vv. 168-173, the Brahma graha's candidates and refusals listed); Yogardha as the mean of the two (v. 174); Kendradi, kendras then panaparas then apoklimas by strength from the stronger of lagna and 7th (vv. 175-177, the lagna-kendradi form some call Narayana); Karaka from the Atmakaraka in karaka order (v. 178); Manduka by jumps of three (vv. 179-180); Shula from the stronger of 2nd and 8th (vv. 181-182); Trikona from the strongest trine (vv. 183-184); Drig by the 9th, 10th and 11th and the rasis they aspect (vv. 185-187); Lagnadi from the lagna advanced by the Moon's nakshatra fraction, with the one balance at birth the text states (vv. 188-190). Every system carries 'assumptions' naming what the text leaves open (Drig and Lagnadi state no year rule, Karaka's count is read inclusive, Manduka's wording does not fit a twelve-rasi jump). Returns the Brahma graha and the BPHS Chara years for all twelve rasis as shared inputs. get_chara_dasha carries the Jaimini Sutras reading and reports this one beside it; neither is picked. Whole-sign houses. No effect is emitted. Edition stated (Santhanam 1984; Sharma numbers this ch. 48).

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.
