The acrimony felt in a heart cannot be healed on its own from those bitter repinings of inner turmoil that keep a person in bondage.
This kind of suffering usually occurs due to some form of injustice; when a wrong has been inflicted by another and the circumstances were too much to bear. Then, when outward aggression was ingested (taken in from words tempered in anger), it’s as if he swallowed a disease that cannot be eradicated through humanistic treatments. For this one was caught off guard when his life took an unexpected turn and was forced to go an unplanned direction because of the thoughtlessness of another; when underhanded behavior brought about unfair consequences that set him with a disadvantage, causing his heart to be overrun with indignation, for he did not foresee this outcome.
