Approximately 43% of us have a mutual reception in our birth chart, ie, when two planets simultaneously occupy each other's sign. It's a powerful combination that links the effects of two houses in a chart, yet it's one of the least understood patterns in astrology. This book, an invaluable reference for any astrologer's library, describes the effects for each of the 66 combinations of house lord exchange.The first section of the book defines mutual reception in various forms, and the rules under which they apply. There's a simple science at work here, and its rigor provides straightforward rules for interpretation. A number of techniques make it clear how to analyse the strength of each mutual reception, identify the control planet and the affected areas of life, and determine the outcome.There are 66 case studies, one for each house exchange combo, eg, exchange of 3rd/8th house lords. First, general rules of interpretation for that (3rd/8th) pattern. Next, the bio of a famous person with that same combo. Then, an analysis of mutual reception in their chart, giving examples of how to apply the various techniques.As a concept, mutual reception is at least 2,000 years old, but there's been very little written about it. This book is one that astrologers will refer to again and again, not only because 40% of clients have one of these combos, but because it's also an education in how astrology can be dignified – as both a scientific map and an artistic palette – on each of which the planets leave their tracks.
