☉
A zodiac set on the stars
Jyotish counts degrees from the actual constellations, where Western astrology starts from the seasons. The gap between them, the ayanamsa, is now close to twenty-four degrees: most people therefore change sun sign when moving from one tradition to the other. Two different frames of reference, not a contradiction.
☾
The Moon first, and its nakshatra
Where the West opens with the Sun, the Indian tradition opens with the Moon and the stellar mansion it occupies. Twenty-seven nakshatras, each with its lord and its temperament: that is the first word of your Vedic portrait.
☸
Time that is mapped, not vague
The Vimshottari dashas divide life into large planetary periods, dated, following a fixed order from your birth. That is the mark of Jyotish: it places things in time rather than merely describing them.
