02 · FOUR PADAS & NAVAMSA (D9) HARMONIC MAPPING

The Four 3° 20' Padas of Rohini & Ninth-Harmonic Dispositors

The lunar mansion Rohini divides into four equal quarters (Padas) of 3° 20' (200 arc-minutes each) that project directly into the Navamsa (D9) harmonic chart. In Rohini, this four-fold partition links the sidereal longitude in Vrishabha to four consecutive Navamsa signs and phonetic seed syllables (Aksharas).

According to Brihat Samhita Chapter 98 Verse 7 and Chapter 101 Verse 4 and Brihat Parashara Hora Shastra Chapter 46 Verses 24 to 27, Rohini carries a dhruva and sthira (fixed and permanent) temperament and a manushya (human) classification. Within the ecliptic structure of Rohini, Pada 2 (13°20'–16°40' Vrishabha) is both Vargottama and Pushkara Navamsa in Taurus (D9).

Pada & Degree Span	Navamsa (`D9`) Sign	`D9` Ruler & Syllable	Classical Pada Delineation
`Pada 1 (10°00' – 13°20' Vrishabha)`	`Mesha (Aries D9)`	Mangala (`"O"`)	Dynamic quarter lending executive drive and entrepreneurial vigor to Rohini agricultural abundance.
`Pada 2 (13°20' – 16°40' Vrishabha)`	`Vrishabha (Taurus D9)`	Shukra (`"Va"`)	Supreme Vargottama and Pushkara quarter maximizing Rohini stability, aesthetic mastery, and wealth.
`Pada 3 (16°40' – 20°00' Vrishabha)`	`Mithuna (The Twins D9)`	Budha (`"Vi"`)	Articulate and commercial quarter uniting Rohini creative fertility with mercantile and poetic skill.
`Pada 4 (20°00' – 23°20' Vrishabha)`	`Karka (Cancer D9)`	Chandra (`"Vu"`)	Double-lunar quarter strengthening maternal serenity, domestic prosperity, and emotional poise in Rohini.
