How nice it is, if you can attend to your own affairs without too much of interference to with other’s business. Here is the advice given by the Buddha:
“One should not regard the faults of others, thing done and left undone by others, but one’s own deeds of commission and omission.”
Again the Buddha says: “He who is observant of other’s faults, and is always irritable his own defilements increase. He is far from the destruction of defilement.”
Further he says: “Easy to see the faults of others; but one’s own is difficult to see. One winnows other’s faults life chaff; but one’ own hides as a crafty fowler covers himself.”
“The noble swerve not from the right path, let happen what may and crave no longer after worldly joys. The wise remain clam and constant in mind alike in joy and in sorrow.”
No one can live in this world without being blamed and criticised by others. Buddha says:
“People blame others for their silence. They blame those who talk much and those in moderation. There is therefore no one in this world who is not blamed.” Further He says: “There never was, nor will be, nor is there now any one who is wholly blamed or wholly praised.” Not all those who criticise you are your enemies. You can make use of the opportunity to find out your own weaknesses which you yourself cannot see.
You should not give up good work just because of criticism. If you have the courage to carry out your good work is spite of criticisms, you are indeed a great man and could succeed everywhere.
