Quick Summary

Jyotisha is the traditional Indian system of astrology, which is similar to Hellenistic astrology. It was transmitted to India around the 2nd and 3rd centuries CE. Indian astrologers adopted the Western zodiac but integrated it with their own philosophical beliefs, such as reincarnation and the doctrine of five elements.

Jyotisha uses a complex methodology that includes lunar mansions (nakshatras), planetary combinations (yogas), and planetary periods (dashas). A key component is the navagraha, a set of nine celestial bodies (Sun, Moon, five planets, and two shadow planets, Rahu and Ketu) believed to influence human lives. These celestial bodies are often depicted as deities in Hindu temples, and rituals are performed to appease them and mitigate negative influences. Astrologers use birth charts, which map the positions of celestial bodies at the moment of birth, to analyze character and predict future events.1234
