Hora Sara | Prithuyasas (Son of Varahamihira) | R. Santhanam | English Astrology Book

Hora Sara (होरासारः) is regarded as one of the most important classical treatises on Hora Shastra, the branch of Vedic Astrology concerned with horoscope interpretation and prediction. The work was composed by Prithuyasas, the distinguished son of the legendary astronomer and astrologer Varahamihira.

The title Hora Sara literally means “The Essence of Hora (Astrology)”, reflecting the author’s intention to present the essential principles of predictive astrology in a concise yet comprehensive form. The text has been admired by scholars for centuries and is considered a natural companion to classics such as Brihat Jataka, Brihat Parashara Hora Shastra, Saravali, and Phaladeepika.

Published by Ranjan Publications, this English edition translated and annotated by R. Santhanam preserves the original Sanskrit text while providing lucid English explanations, making the work accessible to modern students of Jyotisha.

Importance of the Book

Among the classical works of Hindu Astrology, Hora Sara occupies a unique position because it systematically condenses the essential principles of predictive astrology into a practical framework.

According to traditional astrological literature, Prithuyasas drew inspiration from the teachings of his father Varahamihira while presenting his own organized exposition of horoscope analysis. The work discusses planetary nature, yogas, house results, planetary strength, divisional charts, Dashas, and predictive combinations that continue to be studied by astrologers today. The book has also been praised in later classical works such as Hora Ratna, where Prithuyasas is described as occupying a distinguished place among astrologers.
