Pain is truly an experience and is inevitable in this life. However, suffering is optional and happens when we begin to think or say:
this pain is so bad,
why am I having this pain?
What did I do to deserve this pain?
Why did I do wrong to cause this pain?
How do I get rid of this pain?
These delusional thoughts stem from feelings of separation from the Divine, shame of this illusionary separation and fear of divine retribution. Which leads one to believe that the cause of all human suffering and problems is the false belief that one is separated from the Divine.
