Vedic Astrology Glossary
Ascendant / Rising Sign
Lagna is the degree of the zodiac rising on the eastern horizon at the exact moment of birth. It sets the first house of the chart, determines house rulerships, and acts as the chart's structural foundation - the body, self-expression, and life path.
The lagna (ascendant) is the most time-sensitive point in a Vedic chart. It changes approximately every two hours, which is why birth time accuracy is essential in Jyotish.
In Vedic astrology, the lagna does far more than describe appearance or personality surface. The lagna lord - the planet that rules the lagna's rashi - becomes one of the most significant planets in the entire chart. Its placement, dignity, and dasha timing shape the entire life arc.
Each of the 12 lagnas carries distinct qualities:
Planets in the first house (lagna bhava) and aspects to the lagna degree further modify the ascendant's expression.

Vedic Zodiac Sign
Rashi is the Vedic term for zodiac sign. The 12 rashis are calculated using the sidereal zodiac (fixed stars), placing them approximately 23° behind their Western tropical counterparts. In Jyotish, the moon's rashi at birth is often considered more personally significant than the sun's rashi.
Astrological House
A bhava is one of the 12 houses in a Vedic birth chart, each governing a specific domain of life. The bhavas are counted from the lagna (ascendant) and act as the stage on which the planets perform - each planet's effects manifest through the areas of life ruled by its occupied and aspected bhavas.
Lunar Mansion
A nakshatra is one of 27 lunar mansions that divide the zodiac into equal 13°20′ segments. The moon's placement in a nakshatra at birth reveals personality nuances, emotional rhythms, and karmic themes that the broader rashi (zodiac sign) cannot capture.
Planetary Period System
A dasha is a planetary period in Vedic astrology that governs a specific phase of your life. Each planet rules a slice of the 120-year Vimshottari cycle. During its dasha, that planet's themes, strengths, and karmic patterns become the dominant story.
The sun sign changes roughly monthly; lagna changes every two hours. The sun sign describes the ego and purpose; the lagna describes the physical body, temperament, and the overall structure of how life unfolds. In Vedic astrology, lagna is often considered more personally significant than the sun sign.
The lagna degree shifts roughly 1° every four minutes. Without an accurate birth time (ideally within 15-20 minutes), the lagna sign and house cusps may be incorrect, making the chart unreliable for timing events.
No. The natal lagna is fixed at birth. However, certain techniques like Varshaphal (solar return) calculate a lagna for the current year, which shifts annually.
