Hayanaratna: The Jewel of Annual Astrology
by Martin Gansten | 2020 | 195,046 words
This page relates ‘Glossary of Astronomical and AstrologicalTerms’ of the English translation of Balabhadra’s Hayaratna—a significant work within the realm of Indian astrology, particularly focused on the Tajika tradition, which adeptly intertwines ancient Indian and Perso-Arabic astrological knowledge. The Hayaratna acts as both an analytical commentary and a guidebook for practitioners keen on exploring horoscopic astrology, particularly the art of predicting annual occurrences (in Sanskrit known as Varshaphala) based on astrological calculations.
