Title: Best book on practice but be careful
Review: This book is great. It lays out everything that one needs in detail. The only problem is that those inexperienced can cause themselves and others problems and not realize that they have done so until it is too late. This book, being what it is, tends to focus on calling the Petro Lwa. This is not a bad thing but unless the person doing so is experienced, that can be in for an unpleasant surprise. My suggestion for people new to this area is that, if you plan to use this book, follow every single detail.
