The unhealed mind

 An untrained mind is like a child without a parent.
Without guidance, the mind will jump from one drama 
story to the next... stories about fear, negativity, danger, 
worry. All the stories are the thoughts of a frightened child.
A child that lives within you...

Remember the Wizard of Oz? At the end, we see that 
the scary wizard was merely a little man behind a curtain?
Basically all the scary scenarios you waste your life trying to
 protect yourself from, stem from an unhealed mind/child.
 They are not real! You must not give them power. 
Discipline your mind! Heal your child!
