What is that invisible hold that prevents us from doing what we want when someone just says "no"?
There are no chains holding us back. We are not tied up physically. Our body can move with instuctions from our own brain.
But these instructions are theorems deduced and rationalised not only from practical axioms from the brain but also emotional axioms from the heart.
While those emotional axioms could be positive like love, friendship, respect, loyalty, duty, goodwill etc., it could also be negative ones like fear, despair, panic, cowardice, doubt etc..
When positive axioms stay positive and supportive, all is well, everybody is happy. When the positive axioms are misused by others to alter our behaviour or actions it is termed "emotional blackmail" and does no good to the people involved or the relationship.
While Negative axioms obviously have a negative impact, they could also have a positive effect by preventing someone by acting impulsively or making wrong decisions.
In the end a combined input of both practical and emotional reasoning is needed in every action and decision.
Lets not get caught in the shackles of sentiment. Those invisible harnesses that could change a life.
