This is the gist of the practice. You can sit down and use these guided meditations to get started, or to maintain your practice, or to get centered agian, right now in this moment. Some are steeped in Buddhist terminology and structure, which Thich Nhat Hahn explains. But most are non-dogmatic, easily accessible, and potentially life-changing. I've read much by Thich Nhat Hahn, and all of it seems to-the-point and profoundly wise. But this is the book I go back to again and again.
I have enjoyed Thich Nhat Hanh's other books because (the translation of) his writing makes Buddhist thoughts and practices clear and accessible; not too simplistic and not too academic. The guided meditations in this book are no exception. Ranging from very simple to rather complex, each meditation is written in poem like phrases, or stages, with the key words of each in the border off to the side. I have been memorizing the key words and saying them to myself while I run--it makes me much more aware of myself and my surroundings than listening to earphones and makes me concentrate on my breathing, all of which makes the experience more enjoyable.
