One of the best books I've read this year - rich, dense, and illuminating. I liked that these laws and principles - some well known, and some that we take for granted in the background - have been presented agnostic to any particular systems methodology. It feels like a palette I can and will apply to any and every complex situation. The structure of the book is easy to navigate and go back to, as well. I find myself opening it at random and poring through it in retrospect.
I often thought while reading this that it is a sort of scientific guide to shamanism - the act of walking across and between worlds to affect healing and transformation. As such, I found the book not only intellectually stimulating, but spiritually satisfying. It is full of ways of looking and listening, of useful lenses for seeing, and made me aware of many things: ways of seeing that are familiar friends to me, biases that I lean toward and that inhibit my ability to see more clearly (aesthetics, I'm looking at you!), unassuming ways of seeing that I've taken for granted and could now excavate and engage more actively, and some completely new ways of seeing that I will bundle into my toolkit to sharpen, polish, and treasure.
In summary, a book whose utility means I want to put it in my backpack and take it with me wherever I go.
