Sensing / Hearing Gut

As time passed by, constantly listening out for gut reaction at every turn, I noticed that my mind was still when waiting on a reply.
Sure, on the big questions my gut was often loud but on the smaller stuff it was quite faint.
Having a quiet mind magnified the faint replies and often the answer would just pop into my conscience.

Coming back to the question of what is this gut feeling thing that many of us experience?
I have to disagree with the theory that it is just a primitive dynamic of the brain to fight, flight, survive and reproduce.
Sure, that exists and serves humanity well but it cannot tell the future, what will happen later today, next week and in some cases, months to come. Yet that’s what it’s done for me and many others.
What happened next was coincidental…...or was it?
