Self-introspection is very important and needed once in a while. We should think about our weaknesses and we should correct them. When we taste a failure, we need not get worried too much. But we should not ignore the failure also. We should analyse the situation completely and we should understand where we went wrong and see that we will not commit the mistake again in the course of our actions further. If we practice this we need not hear any comments from anybody or need not hear any criticism from others. We should start practising this whenever any issue goes wrong so that we will understand our faults well.
I read some excellent teachings of a great saint. He advised his pupils to cogitate over all sins they might have committed during the day and should start their another day with fresh spirits to do something good for humanity. He emphasised to control our tongue.
