Near Tokyo, lived a great Samurai,  already old,  and  now spending his time teaching young people. Despite his age, the legend was that he could defeat any opponent. One afternoon, a warrior, known for his complete lack of scruples, appeared there. This warrior was famous for using techniques of provocation. He hoped that his opponent made the first move. Gifted  with a privileged intelligence to observe the mistakes of the other warriors, he counterattacked with fulminating speed.
The young and impatient warrior had never lost a fight . Knowing the Samurai’s reputation, he had come to defeat him , and increase his own fame. All the students were against the idea, but the wise old Samurai accepted the challenge. They all went to the town square . There, the young man started insulting the old samurai.

He threw a few rocks in his direction, spat in his face, shouted every insult he knew, offending even his ancestors. For hours he did everything to provoke him, but the wise old man remained impassive.  In the late afternoon,  feeling exhausted and humiliated,  the impetuous warrior gave up and withdrew.

Disappointed that the master had accepted so many insults and so many provocations, the students asked : “As you could bear such indignity?  Why not use your sword, even knowing you might lose the fight, instead of showing cowardly and fearful in front of all of us? ”

” If someone comes to you with a gift, and you do not accept it, whom does the gift belong to ? ” Asked the Samurai. ” To whom tried to deliver it “, said one of the disciples “.  The same goes for envy , anger and insults”, said the master.
When they are not accepted, they continue to belong to whom carries them . Your inner peace depends solely on you. People can not take away your serenity, only if you allow it.
