What is the Navamsa (D9) chart?
Also known as: D9 chart
The Navamsa, or D9, is the most important divisional (varga) chart — each sign is divided into nine parts. It is used especially for marriage, spouse and the deeper strength of planets.
A planet strong in both the Rashi (D1) and Navamsa (D9) is considered genuinely strong (Vargottama when in the same sign in both). The D9 is read alongside the birth chart, never in isolation.
