The book is written in a way that is both very precise and inspiring. Addressed to both lay people and operators, this book is a useful reference for the Breath of Life model of craniosacral work. Within this model, the sacred relationship between spirit and matter is not only thought through and explored, but also professionally used to facilitate the expression of our innate health. The book will also serve as a resource for cranial operators, providing a different perspective to enrich our work.
