As I was looking up Louise Hey, trying to figure out my friend's emotional issue of her chest congestion, I got a message from my friend that she simply needed to calm down and her congestion / cough would go away, as it did in the past.
Eureka!
Her voice sounded normal again!
Think about it - why do we have imbalance in one part of the body and not the other. It is not all physical. Our nerves support life in every cell.
Of course, physical and mental work in reverse as well.
It is all connected. We should be electricians of our own whole being.
I love the TCM (Traditional Chinese Medicine) concept of "tonifying" an organ or supporting emotions.
I remember reading a story of a TCM doctor, in which a girl got well after he told her a funny story. No-one before him could help this girl because no-one took time to find out that some very sad thoughts made her sick.
