Once Lord Buddha along with his disciples went to a village. A person came and started abusing Lord Buddha. He kept the abuses on but Lord Buddha didn't say anything and moved ahead. A disciple, out of curiosity, asked Lord that why didn't you say anything. He replied, “Let me ask a question. suppose somebody gives you a gift but you refuse to take it. Who will keep the gift then?” Disciple answered, “Obviously, the person who wanted to give.” Lord said, “Now, that person wanted to give me abuses but I refused to take those. Now, who actually has the abuses!” I guess we all got the gist of the story. If somebody is trying to offend, somebody is passing some comments, somebody is giving judgements or opinions, better refrain from it. This story is such a simple herb but believe me, it always works. I have tested it at times. Further, as Swami Vivekananda said- “Devote so much time in the progress that you don't get the time to talk/think about others.” Let them do their job and you do what you are good at. calmly, listen and rub it off the shoulders. One day will come when people will keep very high bet for a person who can offend you. And they will get defeated. Each time
