She's a very concise instructor in here, pouring over the fundamentals with a sort of ease and conviction. She explains meditation, koan work, non duality, The Four Noble Truths here; and what's more, Christians don't need to feel they need to give up Christianity to practice Zen. It may be true on a deeper level that in order to truly devote yourself, this might be so. But you can enhance your current religious traditions and spiritual practice with zazen (Zen meditation) at any time. Even contemplating scripture as though they are koans, is a beneficial practice. Christianity has a lot to benefit from Zen, allowing people to place aside desires for achievements (I dare say even heaven) and simply realize your life as this moment. There is no "goal." Only this.
This was an excellent book, and for those with interest in further reading on the matter I recommend Ruben Habito's book "Living Zen, Loving God." He has studied Zen and Christianity for decades, and provides further illuminating insights for Christians on reconciling Zen with Christianity. Anyway, get this book. It's an invaluable tool on the spiritual path.
The writer aproaches the subject from a very human point of view. She is "one of us," battling with fickleness and human nature. And yet, with simple language, practical examples and personal experiences, she helps us to smell the aroma of the spiritual feast that awaits us in zen practice.
While this book probably won't add much to the knowledge or practice of those who are Buddhists or are already practicing Zen regularly, it will be very helpful for Christians who may have an interest in meditation. This book is Hands-On and How-To for those who want to do more than jusy know ABOUT Zen.
