Shani (Saturn) rules Makara and Kumbha, reaches deep exaltation at Tula 20°00' (Libra), and enters deep debilitation at Mesha 20°00' (Aries). In the 120-year Vimshottari Dasha cycle, Shani governs a major planetary period of 19 Years across the lunar mansions Pushya, Anuradha, Uttara Bhadrapada.

In the nine-planet system of Sanskrit positional astronomy, Shani (Śani (Manda), Saturn) is a natural malefic (krura) tamasic arbiter governing longevity span (Ayus), karmic endurance, austerity, structural labor, and third-and-tenth house special aspects.

02 · EPHEMERIS MECHANICS & PRECESSION DIFFERENTIAL

Sidereal Longitude, Synodic Velocity & Dignity Thresholds of Shani

High-precision integration for Shani under DE441 subtracts the Chitrapaksha Lahiri Ayanamsha (24° 13' 18" in October 2026) from the tropical vernal equinox coordinate. In the October 2026 reference epoch snapshot, Shani shifts from tropical Aries 12° 18' 51" to sidereal Meena 18° 05' 33" while moving at a mean sidereal rate of 0° 02' 01" per day.

According to Brihat Parashara Hora Shastra Chapter 3 Verses 34 to 35 and Brihat Jataka Chapter 2 Verses 7 to 14, Shani gains full directional strength in the Seventh House (Yuvati Bhava) and requires at least 5.00 Rupas (300 Virupas) in six-fold Shadbala. For solar proximity and heliacal visibility of Shani, classical mathematical astronomy applies a strict standard: Shani becomes combust within 15°00' of Surya near annual solar conjunction.

Parameter	Specification	Classical Authority
Swakshetra Domicile	`Makara and Kumbha`	Brihat Parashara Hora Shastra Chapter 3 Verses 34 to 35 defines the primary own-sign domicile and planetary rulership of Shani (Saturn) in the sidereal zodiac.

04 · VERBATIM CORPUS FOLIO & DIVISIONAL HARMONICS

Archival Public-Domain Folio Excerpt & Varga Synthesis for Shani

This archival excerpt for Shani is retrieved from the public-domain edition of Phaladeepika (Chapter 16, Verse 30) in jyotish_corpus_core_v3. In divisional horoscopy, the natal Rashi (D1) longitude of Shani is always cross-checked against its Navamsa (D9) dispositor and Dasamsa (D10) occupational strength.

CORPUS PROVENANCE: Phaladeepika | Source ID: archive_dli.ernet.507316 | Chapter 16, Verse 30
"xample 30 The five kinds of connection or relationship recognised between two planets ADHYAYA 16 1 The colour and appearance of the native and the proportions of his body and limbs 2 30 Some effects of the Lagna and the other Bhavas, 31 32 Time when the effects of any Bhava will happen 33"

When Shani occupies identical sidereal signs in both the natal Rashi (D1) and the ninth harmonic Navamsa (D9), Shani attains Vargottama dignity. If Shani stands at its debilitation degree (Mesha 20°00' (Aries)) while its sign dispositor occupies a Kendra from the Lagna or Moon, Phaladeepika confirms Neecha Bhanga Raja Yoga for Shani.
