Just as people listen to the same songs over and over again, that revisit and replay painful memories and experiences in their mind. As a survival mechanism (which is now mostly outdated)the brain remembers traumatic incidents, and remembering them just strengthen the synaptic confections between the Neurons.
These looping thoughts and memories are charged with emotions, and over the time it becomes unnecessary and even damaging and traumatizing to replay them.
This is where we learn that certain practice’s of meditation can help you learn how to separate thoughts from emotions.
The danger is that thoughts without emotions can deaden the personality.
With pure rationality and emotion free content, thoughts become instructions and to-do checklists, and the person becomes hyper-rational, and add a dash of survival instincts, the person can end up being a psychopath or a sociopath.
Improper meditation techniques are dangerous.
But there is a solution at hand.
You must have heard the cliché , “love is all you need”
It is so oversimplified and out of context that it now has become an inane sound bite.
Love is all you need… In essence It means love is the only emotion worth holding on to… That’s all.
If you practice meditation, practice adding some pure love and compassion into it, so that you retain your warmth avd personality avd avoid the pitfalls of hyper-rationality.
If you don’t meditate(you should, by the way), then at least make it a habit to discard all other emotions as soon as they have served their purpose, but hold on to the only safe content free emotion- love.
Just remember: Love is all you need. Love is the only emotion worth holding on to.
