The 12-step program is behaviorally and emotionally oriented. They can be done in conjunction with removing cords, but it is not necessary. My work focuses on solutions; not problems so much, if at all.

Writing letters and burning them does not remove cords in my experience other than making a temporary mental disconnect. If a person believes this then they may be headed into illusory thinking. The writing/burning process does not touch the body processes especially when emotions are blended with the brain of the body (2nd chakra/chi).
