A Janam Kundli (also called a birth chart, horoscope, or natal chart) is a snapshot of the sky at the exact moment and place you were born. In Vedic astrology it is the single most important document — every prediction about career, marriage, wealth, and health is read from it.
What a Kundli actually shows
The chart places the nine grahas (planets) — Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, and Ketu — across the twelve zodiac signs and twelve houses. Where each planet sits, which house it rules, and how planets aspect one another together describe the tendencies of your life.
Why birth time matters most
Your date of birth fixes the planetary positions, but your exact time of birth fixes the ascendant (lagna) — the sign rising on the eastern horizon. The lagna anchors the entire house framework. A difference of a few minutes can shift the ascendant and change house placements, which is why accurate birth time is so important.
Sidereal vs tropical: the ayanamsa
Vedic astrology uses the sidereal zodiac, fixed to the actual stars, rather than the tropical zodiac used in Western astrology. The correction between them is the ayanamsa. Sivayan uses the Lahiri ayanamsa — the standard for Parashara astrology — so your signs and nakshatras match traditional calculation.
The elements to read first
- Lagna (ascendant): your overall constitution and life approach.
- Moon sign (Rashi): your emotional nature and the basis of dasha timing.
- Nakshatra: the lunar mansion the Moon occupies — fine-grained personality and the starting dasha lord.
- The lagna lord and its placement: a quick read of overall strength.
From chart to prediction
A chart on its own is static. Timing comes from the Vimshottari dasha system (planetary periods) and current transits, while strength comes from Shadbala. Combined, they turn the static chart into a timeline of when themes are likely to activate.
