Amazing. Love this book. Life-changing. I want all my women friends to read it. And their teen daughters. Why did it take me so long to find it? Lately, I began to realize that my menses, which align with the moon cycle (ovulate on the full moon and bleed on the dark moon), have a great effect on my energy, attitude, dreams, etc. and I wanted to investigate this more. I came across this book by accident and it called to me. I ordered it almost on a whim without thinking, which is usually my most intuitive way of being. I couldn't wait to dive into it when it arrived. This book is not like others that speak about the best diet or activity for different stages of your cycle. It is not about the way your hormones operate during your cycle. None of that which you'll find in other books. It's psycho-spiritual. No excuses. This book goes into great detail about the the way your spirit and psyche will be effected by the natural rhythms of your moon cycle. It's not called a cycle for nothing. The authors use the seasons as an analogy to help you better understand your cycle and really, yourself. There is a lot of detail too, such as the four seasons, the four transition days between seasons and the 5 chambers of menstruation. I only started tracking all of this, using the book as a guide, and have already found it so useful. Why do I get irritated the day after my period? Because I might not be all that excited about the rising energy I'm feeling. Also, I love the idea that our PMS is natural and can be relieved by acceptance of our cycle as a whole. When I was able to lean into my feelings of turning inward at this time, I felt so much better. As I said, I'm only just started and see so much benefit. Highly recommend.
