This book attempts to explore an ancient technique of predicting an event according to Horary Astrology, which differs from all other predictive techniques of Classical Astrology, whether Western (Tropical) or Indian (Sidereal Zodiac). An astrologer, using Horary Astrology, which is an absolutely structured prediction system, attempts to answer a question posed at a specific moment in time, for which they immediately draw up the sky chart of that moment and try to decode the data at hand. As with all systems, in order to succeed in answering, the astrologer must operate scientifically, based on the absolute knowledge that governs the principles and rules of the system in question, without forgetting that each horoscope is a whole composed of its constituent parts. Thus, keeping in mind the principle of synchronicity and analogy, they understand the connection of the question at the time it was posed with the data of the sky and, essentially, through the instantaneous horoscope they draw up, provide the answer to the questioner, respecting the universe, whose signs they decipher. https://www.lexitipon.gr/product/572/i-wriaia-stin-praxi.html
