02 · FOUR PADAS & NAVAMSA (D9) HARMONIC MAPPING

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

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

According to Brihat Samhita Chapter 98 Verse 11 and Chapter 101 Verse 17 and Brihat Parashara Hora Shastra Chapter 46 Verses 76 to 79, Anuradha carries a mridu and maitra (soft and friendly) temperament and a deva (divine) classification. Within the ecliptic structure of Anuradha, Pada 2 is a Pushkara Navamsa; Pada 4 (13°20'–16°40' Vrishchika) is Vargottama.

Pada & Degree Span	Navamsa (`D9`) Sign	`D9` Ruler & Syllable	Classical Pada Delineation
`Pada 1 (03°20' – 06°40' Vrishchika)`	`Simha (Leo D9)`	Surya (`"Na"`)	Principled quarter channeling Anuradha loyalty into institutional leadership and disciplined self-command.
`Pada 2 (06°40' – 10°00' Vrishchika)`	`Kanya (Virgo D9)`	Budha (`"Ni"`)	Pushkara Navamsa quarter excelling in mathematical research, archival scholarship, and organizational service.
`Pada 3 (10°00' – 13°20' Vrishchika)`	`Tula (Libra D9)`	Shukra (`"Nu"`)	Diplomatic quarter where nakshatra lord Shani is exalted in `D9`, supporting enduring international treaties.
`Pada 4 (13°20' – 16°40' Vrishchika)`	`Vrishchika (Scorpio D9)`	Mangala (`"Ne"`)	Vargottama Scorpio quarter concentrating Anuradha endurance into spiritual sadhana and occult depth.
