One of the most enlightening books I have ever read is Barbara Ann Brennan’s, Hands of Light: A Guide to Healing Through the Human Energy Field, Transworld Publishers Ltd (1993).
Barbara Ann Brennan developed astounding levels of sensitivity as a young child, spending countless hours in an area of wilderness near her own home, eventually developing the ability to close her eyes and ascertain the precise location and movements of animals in the vicinity. She went on to become a research scientist for NASA at the Goddard Space Flight Center following the completion of her Masters in Atmospheric Physics at the University of Wisconsin. Barbara also completed a PhD in Philosophy, a DTh in Theology and qualifications in Counselling.
Barbara currently offers workshops related to the Human Energy Field, Healing and Channeling.
I wholeheartedly recommend this amazing textbook by a truly gifted human being.

Description:
With the clarity of a physicist and the compassion of a gifted healer with more than twenty years of professional experience observing 5,000 clients and students, Barbara Ann Brennan presents the first in-depth study of the human energy field for people who seek happiness and health, and who wish to achieve their full potential. Our physical bodies exist within a larger ‘body’ , a human energy field or aura, which is the vehicle through which we create our experience or reality, including health and illness. It is through this energy field that we have the power to heal ourselves.This energy body – only recently verified by scientists, but long known to healers and mystics – is the starting point of an illness. Here, our most powerful and profound human interactions take place, the precursor and healer of all physiological and emotional disturbances.
Hands of Light offers: * a new paradigm for the human in health, relationships and disease * an understanding of how the human energy field looks and functions * training in the ability to see and interpret auras * medically verified case studies of healing people from all walks of life with a variety of illnesses * guidelines for healing the self and others.
