Before you point out one fault in others, examine thrice whether there is any fault in you

When you come across a big fault in others, just consider it to be trivial. Then you will not be critical. Suppose there is a small fault in you; try to magnify it such that you will never think of committing a similar fault again. By looking at it that way, you will never have occasion to be guilty of the same fault again. On the other hand, if you conceal your fault and try to point out the fault of others, it will not be good either for you or for the others. Do not always lead in pointing out others' faults. Also, if anyone points out a fault in you, humbly accept it, because you, by yourself, will not be able to find out where you are in the wrong. It is difficult to identify your own faults, because your vision is directed outward, you will not be able to find the fault in your own nature!
