While this book gives a good overview into Reiki, it's not particularly informative for someone who is seeking in-depth information on using the traditional Usui system. The pictures are lovely and it's well laid out, but it doesn't divulge any information you can't find anywhere on the Internet for free. This is a good book to introduce clients to Reiki, or to see if someone is interested in studying it. It's not a good resource if you are seeking deeper information on use or teaching of Usui Reiki.
