This is a book about Zen, written for people who have never read a book about Zen, and for people who have read too many.
It is not a manual. It is not a self-help guide. It will not teach you to optimize your mornings, silence your thoughts, or achieve anything in particular. If you are looking for that kind of book, there are thousands of them, and they are waiting for you, and they will probably disappoint you in the familiar way.
This book is something smaller and more honest: a companion for people who sense that something is missing — not in their circumstances, but somewhere closer. And a warning for people who are looking for that something in the wrong places.
The book is in four parts. The first looks honestly at the shape of modern suffering. The second describes the spiritual marketplace and its dangers. The third points at what genuine practice actually offers. The fourth describes one person's practice, in detail, as one example among the many a reader could find.
Read it slowly. Set it down. Pick it up again. Do not try to finish it.
A reader who finishes this book should be more free. Including more free from this book.
