s/t: The Autobiography of a Couple
The Dyadic cyclone is the combination of two personal centres. In this book it's a male & female combination--two rotating cyclones with their enclosed centres, one rotating to the right, the other rotating to the left. In The Dyadic Cyclone, Toni & John ask the question 'Is it possible to merge two centres, two cyclones, one male, one female, in such a way that there can be a rising, quiet centre shared by both?' In our five years together, we have sought means to achieve this between us. This book is the story of that five years insofar as we can tell it at this time.
