When the fear of feeling our emotional and physical pain becomes more significant than our intention to heal, we fall into a state of resistance and contraction. When we resist and contract we fail to release the energy of this pain entirely, and part or all of it remains in the body.
The ongoing presence of this energy in our body literally influences our lives on a daily basis through our thoughts, choices, and actions. It can also affect the physical body in a myriad of ways including illness.
It is not until it comes back into our awareness through self-inquiry or another event that brings it up into our conscious awareness that we can release it. At that time it must be felt and released, or it will remain stuck indefinitely and impacting our lives in some way.
