We call that sabotage. Think for example of those important matters that you keep postponing, changes you want to make in your life but that never seem to last very long. Sabotage can also work on a physical level. These are all symptoms of sabotage. This sabotage can be caused by emotional blockades.
Blockades arise during our life, by unprocessed emotions from negative or painful experiences.
These experiences are stored in our subconscious mind and can sabotage us in other situations. The emotions from these experiences are related to our organs. For instance, the heart relates to emotions such as hurt and feeling lost, while the liver relates to feelings of anger and hate. Suppose you are a real professional. You know you are fully qualified for that perfect you that you really want.
