From Chapter 9 "Mind Games"

So the decision to turn my will over to His care begins by desiring to replace my thoughts with His thoughts. The war of our affliction began in the mind and now the outer shell reflects the way we think. Change requires going to the source and like the undesirable vine in our garden if we only clip the leaves the vine will appear dead but the root will produce the leaves again when the time is right. We must uncover the root to destroy the vine. It is my prayer that we find the root of our undesirable vine.
