The strongest expression of any two planets occurs when they are conjunct. In this book, Mrs. Leinbach describes planetary relationships in conjunction, where the interaction is strongest. Conjunctions in a chart strongly characterize an individual, intensifying the influence of the two planets involved. Also, understanding the nature of the conjunction can inform one's understanding of the interaction of two planets in terms of whatever other aspect (such as the trine or square) might be found. Planets & Asteroids, Relationships in Conjunction is also an essential tool for understanding how two people interact with each other based upon the conjunctions between their two charts. Conjunctions between two individual charts are one of the most significant factors in understanding the way two people will relate to each other. This book was first published in 1974. Esther V. Leinbach was one of the first astrologers to write about the four major asteroids, Ceres, Juno, Pallas and Vesta. This newly updated and revised editon now also includes Mrs. Leinbach's interpretation of the recently discovered minor planet, Chiron.
This book is a bit older, but as an astrologer, I still found some really great takeaways and insights in it. Esther has her own unique take on asteroids that goes against the usual status quo, which actually made it a lot more interesting to read. She touches on themes I hadn't run across yet.
Considering when it was written, I think it's a really solid book. Like with any astrology book, you just take what clicks with you and leave the rest. Overall, I'd say it's a good read!
