Gulika is a sensitive point in the Zodiac emerging at different points on different days. Its longitude is calculated like that of the Planets and is marked in the horoscope along with the other longitudes. Though rich and varied effects – good and bad – are attributed to Gulika in Kerala basic treatises, like Prasnamarga, other basic treatises in Astrology like Parasahora etc. are silent on Gulika. The present work Gulika in Astrology is a compendium of all materials available in the treatises. Perhaps at present this is the only work of its kind.
