Jyotisha (spelt correctly as ज्योतिष jyotiṣa) is the traditional Hindu system of astronomy and astrology, often referred to in English as Vedic astrology or Indian astrology. The term is derived from the Sanskrit word ज्योति jyoti, meaning “light” or “heavenly body,” and it is frequently described as शस्त्र śāstra meaning science → hence a ‘science of light’.
Key Aspects of Jyotisha
- The “Eye” of the Vedas: It is one of the six Vedangas (auxiliary disciplines) of the Vedas and is metaphorically called the “Eye of the Veda Purusha” because it allows one to see the “unseen” or the timing of destiny.
- Primary Purpose: Historically, it was used to create calendars and calculate the most auspicious times (Muhurta) for performing Vedic rituals and sacrifices.
- Connection to Karma: It is rooted in the belief that celestial movements reflect a person’s Karma-phala (the fruits of past actions). Practitioners use it to gain insight into a person’s character, life path, and spiritual journey.
- Comparison to Western Astrology: Unlike Western astrology, which uses the Tropical zodiac (fixed to the seasons), Jyotisha uses the Sidereal zodiac, which accounts for the precession of the equinoxes to align more closely with the actual observable constellations.
Three Main Branches (Skandhas)
Traditional Jyotisha is divided into three major categories:
- Siddhanta (Astronomy): Mathematical calculations of planetary positions and paths.
- Samhita (Natural Astrology): The study of celestial movements and their collective impact on the world, such as weather, eclipses, and omens.
- Hora (Horoscopic Astrology): Predictive astrology for individuals, including the study of birth charts that are called Janma Kundali or Jātaka.
