This is not a "how-to" book on dowsing, but more a spiritual guide directed towards dowsers. It may, however, have fairly practical value to many dowsers who are struggling to master this etheric art. This is because beyond the Zen "Beginner's Mind" or colloquial "Beginner's Luck" stage when everything seems to work, comes a more difficult phase when deep struggles emerge between the logical and intuitive facets of the mind.
At this point one must honestly review one's motivations and goals, and decide to "put one's heart into it" or not. Without this honesty, commitment, humility and dedication, I don't think the necessary connections can be established and maintained in one's psyche to be a good dowser. This is because with dowsing it's an all-or-nothing issue - once confronted with the true nature of dowsing, one can no longer claim ignorance to its underlying miraculous nature. At that point one must decide whether to surrender one's ego, or simply give up the game.
There are many ideas presented in this book in a rather friendly and rambling style, like an after-dinner conversation in the living room. But any book that recommends starting the day with the prayer "Allow me to be of service today" shows its true colors.
