You must learn how to guard yourself from unjust criticism and how to make use of constructive criticism. You must look objectively at criticism that others give you. If the criticism that comes to you is just, well-founded and given with good intention, then accept that criticism and put it to use. However, if the criticism that comes to you is unjust, ill-founded and given with bad intention, you are under no obligation to accept this kind of criticism. If you know that your attitude is correct and appreciated by wise and cultured people, then do not worry about ill-founded criticism. Your understanding of both constructive and destructive criticism is important.
The Buddha says:
There is no one who is not blamed in this world.
