Reiki Books

I have read great Reiki books.  Some in English, some in Spanish. 

Spanish:

1. Reiki Universal.  Johnny de'Carli.  This is a simple and great book for all of those who wish to know more about reiki, are thinking on starting reiki or have been attuned for a Level 1 Reiki.
2. Reiki.  Sistema Tradicional Japonés.  Johnny de'Carli. This a more throrough book.  With great tips and techniques for all Levels.

English

1. Essential Reiki.  Diane Stein.  This is a great book for begginers and Attuned Reiki practicioners.

I also suggest that you read at loeast a simple book about chakras.  It is important to know at least the basics of chakras to better work and comprehend Reiki.
