Nasreddin Tusi said:
If the lack of awareness of one's own faults is a disease, it is said to cure it:
That person should find a virtuous and perfect friend.
After sitting and communicating with him for a long time, he should allow him to tell his mistakes.
Let him correct these mistakes. This is also the help and loyalty of a friend.
Make a firm agreement with him about this, not to hide anything, not to say that there is nothing wrong with you.
