You cannot completely resolve any difficult obstacle in your life without feeling all the emotions associated with that event. They must be fully felt and then released. Otherwise, the leftover energy of the unprocessed emotions will be stored in your body. When this energy is strong enough, it will influence your choices and behaviors in life, and it can even begin to affect your health. Sometimes you can see these influences, but usually, it happens below your level of awareness, unless you are paying attention.
Remember that your thoughts can fool you into thinking that you have worked through everything. However, if you did not, this residual emotional energy will reinsert itself back into your life through your thoughts and actions. This is why paying attention and being aware of your thoughts and actions is so important. Through this attention, it will be revealed to you if you have more emotion or energy to release. Know that you cannot be fooled by your thoughts if you watch them without attachment.
