213. Amīr al-mu’minīn, peace be upon him, said: Ignore pain otherwise you will never be happy. [Or according to another reading): Ignore pain and grief; you will ever be happy.] 
 Every individual has some shortcomings or other. If a person keeps aloof from others because of their faults and weakness, he will, by and by, lose all his friends and become lonely and forlorn in this world and thus his life will become bitter and his worries will multiply. At such a moment he should realize that in this society he cannot get angels with whom he may never have any cause of complaint, that he has to live among these very people and to pass his life with them. Therefore, as far as possible he should ignore their shortcomings and pay no regard to the troubles inflicted by them.
