No tree it is said, can grow to heaven unless its roots reach down to hell.

People will do anything no matter how absurd, in order to avoid not facing their own soul.
One does not become enlightened by imagining figures of light, but by making the darkness conscious.
Carl Gustav Jung  (26 July 1875 – 6 June 1961) He was a Swiss psychiatrist, and the founder of analytical psychology.

I think I understand this concept. I think that I understand it very well as I detail the feelings that I experience from day to day.  It has many names and it has the umbrella name of anxiety. According to many texts I have read and according to the description below from this very helpful website.  http://www.mentalhelp.net/poc/view_doc.php?type=doc&id=13741&cn=9 / http://www.mentalhelp.net/

Anxiety Disorders
The term "anxiety disorders" covers a range of conditions that impairs someone's ability to function, ranging from Simple Phobias (intense fear of a particular item or situation such as spiders or bridges), Panic Disorder / Generalised Anxiety Disorder (a intense, all encompassing sense of worry), Obsessive-Compulsive Disorder (a person experiences obsessions, or repeated unwanted and intrusive thoughts and engages in compulsions, or repetitive and ritualistic anxiety-reducing behaviours), P.T.S.D. , and Social Phobia (intense anxiety created by social or public situations). Even though these disorders have very different symptoms, they all share a cardinal feature: intense, extreme, and disabling anxiety that appears in anticipation of or in response to situations which does not subside over time.
Individuals with anxiety disorders may feel overwhelmed, ashamed, or frustrated that they are unable to control their symptoms. Many individuals with severe anxiety symptoms also become socially isolated and/or try to relieve their feelings by using alcohol and/or other substances. These features of anxiety disorders can lead someone to attempt or commit suicide.
Post-Traumatic Stress Disorder
P.T.S.D. is an extreme reaction to a traumatic event characterised by flashbacks (traumatic memories), trauma-themed nightmares, extreme jumpiness, and difficulties managing emotions. Individuals with P.T.S.D. have the highest rate of suicide when compared to all other anxiety disorders.
