I like this book a lot. For me, it symbolizes a way to increase my own vitality, while also increasing the health of other people at the same time. I look forward to putting what it describes into practice. Although I am not far advanced in this at all, I have seen people who, through their hard work, have really latched onto something real and quite useful for other people. I hope to count myself among them. Buy the book if you have an interest in that direction and are willing to learn about things from another angle!
