Vedic science
Jyotisha ज्योतिष
Vedic astrology - the science of cosmic timing
Reading the position of the nine planets (navagraha), 27 nakshatras, and 12 rashis at the moment of birth to understand a person's karma, talents, challenges, and timing.
Parent Veda
One of the six Vedangas (limbs of the Veda); originally an Upaveda
Founders / systematisers
Surya himself (the sun god) is said to have taught the science to Maya the architect; Parashara (c. 1500 BCE) and Varahamihira (505–587 CE) are the great human systematisers.
Introduction
Jyotisha means "the science of light". Unlike Western tropical astrology which uses the sun-sign, Vedic astrology uses the sidereal zodiac - anchored to the actual fixed stars - and emphasises the position of the moon at birth (janma rashi).
It rests on three foundations: the 12 rashis (zodiac signs), the 27 nakshatras (lunar mansions), and the 9 grahas (the seven visible planets plus the two lunar nodes Rahu and Ketu). Time itself is measured by the panchang - five limbs of the lunar calendar.
Jyotisha is not fortune-telling. It is a map of karma - what tendencies you bring into this life, what dasha (planetary period) you are running, what timings are favourable for which acts. A serious Jyotisha consultation feels less like prediction and more like reading the score of a symphony you are already playing.
Key concepts
27 Nakshatras
Lunar mansions, each 13°20' of the zodiac. Each has a deity, ruling planet, and quality. Your janma nakshatra (the moon's position at birth) is the most personally important point.
9 Grahas (navagraha)
Surya, Chandra, Mangala, Budha, Brihaspati, Shukra, Shani, Rahu, Ketu. The seven visible planets plus the two lunar nodes (ascending and descending).
Dasha system
A planetary period system. Each person passes through long dashas (Saturn 19 years, Venus 20, Sun 6, Moon 10, etc.) that colour the years of life.
12 Bhavas (houses)
The chart is divided into 12 houses - each governing a domain of life (self, wealth, siblings, mother, children, enemies, marriage, longevity, dharma, career, gains, losses/liberation).
Panchang - five limbs
Tithi (lunar day), vara (weekday), nakshatra (lunar mansion), yoga (sun-moon angle), karana (half-tithi). Together they determine the auspicious moment (muhurta) for any new venture.
Yogas
Specific combinations of planets in a chart that produce reliable effects - Raja Yoga (royal), Dhana Yoga (wealth), Gajakesari Yoga, Pancha-mahapurusha Yoga, etc.
