VERBATIM CORPUS FOLIO & CHART SYNTHESISArchival Public-Domain Folio Excerpt for Ashtottari Dasha (108-Year Cycle)
This archival verse passage for Ashtottari Dasha (108-Year Cycle) (DASHA-02) is extracted from the public-domain edition of Brihat Parashara Hora Shastra (Chapter 3, Verse 41) indexed in jyotish_corpus_core_v3.
CORPUSPROVENANCE: Brihat Parashara Hora Shastra | SourceID: archive_brihat-parashara-hora-sastra | Chapter 3, Verse 41 "plants, Guru fruitful ones and Budh fruitless ones 41-44 Other matters Rahu rules the outcaste, while Ketu governs mixed caste ani and the nodes indicate ant-hills Rahu denotes multi-coloured clothes and Ketu rags Lead and blue gem belong to Rahu and Ketu S rya, Candr, Mangal, Budh, Guru, ukr and ani in"
Because Ashtottari alternates between four-nakshatra blocks (6y Sun, 8y Mars, 10y Saturn, 12y Rahu) and three-nakshatra blocks (15y Moon, 17y Mercury, 19y Jupiter, 21y Venus), comparing Ashtottari against Vimshottari provides a second independent clock for conditional horoscopes.
