Sequel to Hands of Light
Format: Paperback
Hands of Light has been widely recognized as the foundational text merging the Eastern approach to healing through cleansing and balancing a person's chakras and auras with the Western approach to healing through re-tuning a person's electromagnetic frequencies by applying the principles of quantum physics. Barbara's sequel, Light Emerging, further amplifies and extends these concepts. Specifically, she elaborates on the applications of the Holographic Model, the Creative Process and the mechanisms of Spiritual Guidance. She defines and diagrams the four dimensions of humanity at the Physical, Auric, Harac and Core Star levels. Through these four dimensions, average humans, once healed and balanced, can mature to be channels of energy, connecting heaven to earth vertically, and connecting all of humanity horizontally. The whole of Barbara's teaching can be incorporated into these four simple, clear and deeply profound diagrams. Since her previous book, Barbara set aside her private practice to establish a four-year university-level program to train and accredit healing practitioners to apply these disciplines. This book incorporates the further insights and experiences she gained through developing her School. Light Emerging is written specifically to instruct readers on how to self-heal and to give readers a preview on the commitment required to becoming a healing practitioner. This book is not intended to replace her School's four-year degree in healing. Appendix C offers links to current lists of her practicing graduates, by city and state. There is no duplication between her books. I personally benefited by reading and studying them side by side. I have also called a number of her graduates here in California and confirm they have both the meticulous training and proper motives to follow in Barbara Ann Brennon's footsteps. No fiction here. This book exemplifies the theory and practice of genuine physical, psychological and spiritual healing, either through self-study or through a practitioner.

A very erudite validation of alternative energy healing
Format: Paperback
I have not got very far in reading since I am reading in parallel Rosalyn Bruyere's "Wheels of Light", but so far find it more accessible than Ms Brennan's first book, "Hands of Light" and this is quite natural since I am not a scientist. But I can't help feeling that in many instances of alternative healing modalities, a personal experience of a natural gift of healing is being made to appear to the general public as a complex and costly necessity for effecting the healing that is a natural propensity of one's body if not hindered by pre-conditioning. Notwithstanding this, I like this book because is speaks to a personal experience of healing energy as subtle sensation/LIGHT which I see as merely awaiting universal acknowledgment that ALL is Light, appearances to the contrary to be shattered by such acknowledgment, and all advances in science that corroborate that fact is welcome.

A great resource for those on their own healing journey and others
Format: Kindle
It is said that energy medicine is the next frontier of medicine. This book helps to explain why. Barbara has decades of experience working with physics, counseling, high sense perception, as well as watching and assisting thousands of people manage their energy field for wellness. Her first book "Hands of Light" is more like a technical manual (and fascinating). This book is written for all of us - on our own healing journey and how we can **empower our selves in our own health and well being**. How we view and assimilate western concepts of "medicine", medication, therapy and other interactions into our own self has more to do with health than the intervention alone. It is also a great resource for healers, psychologists, medical professionals - anyone in a service profession aimed to assist others in their health and wellness. The concepts are powerful when practiced with intention and depth of management of our own field. We can help others by simply managing our own awareness, mindfulness and field.
