Sati might have concluded that she would take the risk of going to her fathers house, and even if her father spoke unkindly against her she would be tolerant, as a son sometimes tolerates the reproaches of his parents. But Lord Siva reminded her that she would not be able to tolerate such unkind words because natural psychology dictates that although one can suffer harm from an enemy and not mind so much because pain inflicted by an enemy is natural, when one is hurt by the strong words of a relative, one suffers the effects continually, day and night, and sometimes the injury becomes so intolerable that one commits suicide.
