This book was recommended by my friend who said it changed her life. The book offers few models of what men and women are, and what roles they should play in life and relationships. The author doesn't bother explaining or backing up any of it, so as a reader you can only take it at face value.
Author uses sexual language a lot. For example "penetrate" is used 31 times. The book is written in a beautiful metaphorical language which is open to different interpretations. I'm yet to understand what "penetrate the world" means.
Like a popular saying "All models are wrong, but some are useful", some of the book's models can be useful. Some definitely resonated with my experience. The problem is the offered models are on a high level. Think of them as symptoms. It's easy to observe the symptoms and think you understand a disease. However it's not. If you don't know what a bacteria is, you will think "bad spirits" are the cause.
I think advice like "men should do X" with a "just because" reason is dangerous even if it's correct. For each one valid model, there are ten invalid ones.
Overall it's an interesting read. I'd like this book to be rewritten with more substance.
