Yoga Karaka (Lagna-specific) [Parashari]

get_yoga_karaka

[Parashari] Yoga karaka by lagna, as BPHS ch. 34 names it (Santhanam; ch. 36 in Sharma), read from the verses. The KP corpus does not use the concept, so never present it as a KP rule. BPHS gives two definitions: the pair rule (34.11-12, a kendra lord and a kona lord in exchange, together, one in the other's sign or in full mutual aspect) and the single-planet rule (34.13, one planet owning both a kendra and a kona), and 34.15 denies the yoga where the lords also own an evil house. Its per-lagna verses name a single planet for Taurus, Cancer, Capricorn and Aquarius, a PAIR (the 9th lord with the 10th lord) for Virgo, Libra, Scorpio, Sagittarius and Pisces, and none for Aries, Gemini and Leo. Returns 'yogaKaraka' (one planet, null where none is named) with 'yogaKarakaSource'; 'yogaKarakaPair' (the pair, never split into a primary and a secondary, with whether the two are related in this chart, reported and gating nothing); 'bphs' (what the verse names and the planets it calls auspicious, neutral or killers); 'readings' (every stated reading, the verse first: Leo Mars and Libra Saturn are derived from 34.13, and Libra and Aquarius are disputed, so give both readings); 'lagnaLord' (the lagna lord does not count on its own at the verse, and the later and modern readings that count it are listed apart); 'tableVariant' (this tool's earlier fixed table, whole, with the names no text supports marked unsourced); 'definitions'; 'placement' (KP house and whole-sign house); whether the running mahadasha or antardasha lord is a named yoga karaka (either member of a pair); 'rationale'; and 'definitionCheck' (sign-lordship arithmetic). 'secondaryYogaKaraka' is retired and always null. Say which reading you used.
