The Navamsa (D9) chart is the most important divisional chart in Vedic astrology. It reveals:

Marriage & Spouse: Nature, appearance, and qualities of life partner
Dharma: One's righteous path and spiritual purpose
Planetary Strength: Planets gain or lose strength based on D9 placement
Vargottama: Planets in same sign in both D1 and D9 (highly auspicious)
