I just came across this book....i haven't read it, but heard it was very good. Reiki, The Ultimate Guide-- Learn Sacred Symbols & Attunements plus Reiki Secrets You Should Know by Steve Murray
It is especially for those wishing to participate in spiritual work in classes that one can not afford, even though one feels that one is spiritually ready to receive the sacred knowledge. It is the first book I am aware of for Reiki attunements, and teaches how to use and respect the sacred symbols. Some Reiki masters do not like this book, because it is taking business away from them. I heard he also has videos and DVD's that actually attune you without going to a workshop. This is a good thing!!! it will get the work out there, into the hands of many more seekers.
