Throughout our life we are involved in many relationships. We have relationships with lovers, our families, friends, bosses and colleagues. As astrologers we look to the heavens to comprehend the nature of these connections. We want to understand why we have fallen in love with a particular person and why that love then withered and died, or why we have formed lifelong friendships with certain people. We want to know what makes others tick, what they feel about us, why we feel the way we do about them. We want to know the answer to the question ‘Do you love me?’ Synastry is the technique by which we can gain answers to these questions. In this book, John Green teaches the astrology student how to compare our charts with those of others in order to gain an understanding of the various types of relationships we encounter in our own life and those of our clients. Based on a series of online seminars given by John to students, the text explains how by looking into the psychological nature of these relationships we can gain deep insights into ourselves, learn about the patterns we fall into within relationships and make changes to improve our interactions with others. John Green has been involved with astrology for over 25 years. He currently works as an astrology consultant and as a tutor for the Centre for Psychological Astrology. He is the creator of their highly successful online Foundation and Intermediate courses in psychological astrology. He has lectured at astrological conferences in the UK and US and was the editor of The Astrological Journal from 2008 to 2013.
