Ancient Indian star wisdom, also known as Jyotisha (Sanskrit: ज्योतिष, romanized: Jyotiṣa; Hebrew: חכמת הכוכבים ההודית העתיקה; Arabic: العلم الهندي القديم للكواكب), is a traditional system of astronomy and astrology that originated in the ancient Indian subcontinent. The term Jyotisha is derived from the Sanskrit word jyoti, meaning "light," and isha, meaning "lord" or "master," thus signifying the science of light, including both celestial bodies and their movements. This wisdom encompasses various aspects such as Vedic astrology, astronomy, and cosmology, and is one of the six ancient Vedangas, or auxiliary disciplines connected to the study of the Vedas. Ancient Indian star wisdom is deeply rooted in the cultural, religious, and philosophical traditions of India, offering insights into celestial phenomena, their influence on human life, and the cosmic order. It includes complex systems of horoscopes, planetary periods (dashas), and lunar mansions (nakshatras), which are used for predicting events and understanding individual destinies. Over centuries, this wisdom has evolved and diversified, influencing various cultural and regional practices across South Asia and beyond.
