Returning injury for injury, harm for harm,
or insult for insult only adds to the Karmic burden,
which has to be endured and eliminated in future lives.
This burden is termed "Aagaami" (impending).
You can't escape the task of undergoing the
consequences of your thought, word, and deed in due course.
Paying evil for evil can never lighten the weight of Karma;
it will only become heavier. It might confer immediate relief
and contentment, but it can only make you suffer later.
Forbearance, therefore, instructs you to do good even to those who injure you.
