Fear and its Irrationality
I think some of our problems are rooted in fear, and most of the fears are irrational and made up by our thoughts. Usually, we tend to run away from fears, causing fear to be entrenched deeper and deeper.
Question is, is it possible to find the root and cause of fear and its irritionality? Perhaps yes, by not running away from the fear, but taking it head-on, it is possible to find the root and cause of fear and its irrationality, and get rid of the fears and the resulting illusion of problems, altogether.

Yes it takes a brave heart and focused mind to achieve it. With persistence, acceptance and execution.
Fear is a deep rooted emotion in our brains.
Agree
I believe that – ‘Every problem (fear and irrationality) always has Root Cause.’ It is we, who do the Root Cause Analysis.
A simple way is asking yourself, “WHY???” 5 times. You should get the root cause.
