So what is in The Healing Codes manual, as opposed to the book? The actual 'codes' are sets of hand positions in relation to the four healing centers.There are 12 pairs of codes, each pair addressing one of 12 'spiritual' issues that the authors consider underpin every physical and emotional problem. The Healing Codes categories are divided into two groups - those the authors see as 'inhibitors to healing' and those they see as the 'core healing virtues'. The inhibitors are; unforgiveness, harmful actions, and unhealthy beliefs. The core healing virtues include qualities such as joy, peace, patience, kindness, humility etc. For healing to take place, the inhibitors have to be removed from the 'heart' and the healing virtues must be installed.
