The only way to healing at a cellular level is to come face to face with what you are feeling, finding the root cause and making your peace, Bays says.
She is supported in her belief by Dr Deepak Chopra and Dr Candace Peart whose Nobel Prize nominated research, Molecules of Emotion, describes how emotions affect our bodies at a cellular level.
Peart's study found that even if a condition heals, it may reappear if the memory of that trauma is retained in the cells.
"The Journey," Peart has said, "will inspire millions, not only those with physical challenges in their lives but those seeking spiritual understanding."
Meanwhile in Ireland, Dr Paddy Rudden, a GP who has been working in the northeast region for 32 years, says the future of medicine involves the integration of mind, spirit and body.
"Doctors want to heal more than cure but the problem is a lot of our innate abilities to heal people are trained out of us by the system," he says.
"We're well equipped to fix things but healing is much deeper and involves the mind, body and spirit.
"The new physics supports this point of view and some of the best writing on the subject is by physicists and not by doctors," according to Rudden.
"One of the most respected authorities on these matters is Dr Candace Peart, a highly respected molecular biologist in the US," he says.
