Canonical Definition · Antardasha, Pratyantardasha & Sookshma Timing (DASHA-06)

Codified in Brihat Parashara Hora Shastra Chapters 52–60 & Phaladeepika Chapter 20 and Sarvartha Chintamani Chapter 16 & Hora Ratnam, Antardasha, Pratyantardasha & Sookshma Timing operates under the mathematical invariant T_sub = (T_parent × T_lord) / 120 ; Shadashtaka (6/8) & Dwirdwadasha (2/12) Axes: Within the 120-year Vimshottari structure, every sub-period duration is computed by multiplying the parent period length by the sub-lord's Mahadasha years and dividing by 120: Antardasha = (M × A) / 120 years, Pratyantardasha = (M × A × P) / 14,400 years, and Sookshma Dasha = (M × A × P × S) / 1,728,000 years.

Mathematical Formulation & Structural Rules of Antardasha, Pratyantardasha & Sookshma Timing

Classical texts evaluate sub-period quality both by the natural beneficence of the Antardasha lord, but by its geometric vector measured from the Mahadasha lord (Dasha Lagna): when the Antardasha lord occupies the fifth, ninth, fourth, seventh, or tenth house from the Mahadasha lord and shares temporal friendship (Tatkalika Maitri), it delivers constructive fruition. Conversely, when the Mahadasha and Antardasha lords stand in mutual 6/8 (Shadashtaka) or 2/12 (Dwirdwadasha) positions without Raja Yoga linkage, friction ensues—even between two natural benefics such as Jupiter and Venus.

The structural matrix below details the exact computational parameters, degree thresholds, and classical interpretive clauses for Antardasha, Pratyantardasha & Sookshma Timing (DASHA-06) as preserved in Brihat Parashara Hora Shastra Chapters 52–60 & Phaladeepika Chapter 20.

Chronological Tier Proportional Formula (120y Base) Duration Span (Min – Max) Classical Geometric Rule (BPHS Chapter 52)
Mahadasha (Dasha Pati) M_years (6y Sun to 20y Venus) 6.00 Years – 20.00 Years Sets the overarching house, Nakshatra dispositor, and Varga dignity ceiling in classical Jyotish horoscopy.
Antardasha (Bhukti Pati) (M × A) / 120 Years (or M × A × 3 Days) 3m 18d (Sun-Sun) – 3y 4m 0d (Ven-Ven) Evaluated both from Janma Lagna and from Mahadasha Lord as temporary Ascendant in classical Jyotish horoscopy.
Pratyantardasha (PD) (Bhukti_days × P) / 120 Days 5.4 Days (Sun-Sun-Sun) – 200 Days (Ven-Ven-Ven) Delivers the physical manifestation when supported by transit bindus >= 4 in BAV in classical Jyotish horoscopy.
Shadashtaka (6/8) Filter Distance between MD Lord and AD Lord = 6 or 8 signs Applies across all 9 × 9 = 81 Bhukti Pairs 6/8 and 2/12 sub-periods demand remedial discipline unless cancelled by Viparita or Raja Yoga in classical Jyotish horoscopy.

This archival verse passage for Antardasha, Pratyantardasha & Sookshma Timing (DASHA-06) is extracted from the public-domain edition of Brihat Parashara Hora Shastra (Chapter 3, Verse 41) indexed in jyotish_corpus_core_v3.

CORPUS PROVENANCE: Brihat Parashara Hora Shastra | Source ID: 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"

For day-level event verification, the astronomer overlays the active Pratyantardasha lord with the slow Gochara transits of Saturn and Jupiter across the Kakshya (3° 45' Ashtakavarga eighth-parts) of the natal chart.
