The soul is made up of your mind, your thought process, and your emotions. This aspect is just as important your physical body.
When you soul is damaged then your physical body becomes effected too. This comes in the form of depression, anxiety, past experiences, etc. anything that effects the way you think, the way you act, and your emotions. To better heal your soul you have to first identify what the issue is then address the root cause of the problem.
I would like to refer this as the "Heart of the Matter." When your heart (soul) is damaged then your whole body doesn't operate correctly.
