Wheels Of Life - Anodea Judith.

This book is a classic and a "must-read" for all who want to understand chakras -- the seven energy centers of the body. It is these energy centers that generate the auras that are described in TCP. The book examines the chakras from many different perspectives, discussing some of the traditional hindu concepts of energy and tying in much practical information, including meditations and exercises for chakra balancing. Because it is so incredibly well researched, it serves to tie together much information often encountered in "new age" spirituality and presents it in a unified, coherent and easily understood package.
