There are all too many people who build what starts as a trivial ‘slight’, into a lifelong anger. Sometimes, the origin of the ‘slight’ has long been forgotten. But the anger stays.
We know from recent studies of the brain, that bad things stick in ones’ brain like velcro. The good that follows in life, slides off the brain as if it was trying to attach to teflon. That in large part is why old hurts stick around far too long, unless they are actively attacked with multiple positive inputs.
It has been demonstrated that in order to overcome a negative bias in the brain, a bias derived from a negative experience such as the ‘slight’ mentioned above, multiple positive experiences and thoughts are needed to turn the negative into a positive feeling. Dismissing that hurt that one carries for years, requires active, intentional, positive thoughts. In the absence of this process, the negativity becomes increasingly part of the neural pattern of the brain, increasingly difficult to overcome.
Hence, if we do nothing to regain a positive state of mind, we can go through life carrying a soul-devouring negativity, a negativity that, like a dark cloud, dims the quality of life we aspire to have.
