No person sees all of his faults. Every person considers himself righteous an feels whatever he does is correct. For every act a person does, he has a thousand excuses and rationalizations. A person does not see what goes against his prejudices. Other people can be much more objective about you and can find your wrongdoings and faults. Hence, be willing to listen to what an admonisher has to say.
A person’s soul has a spark of divinity. Forgetting one’s lofty identity, one might pick up major faults and bad habits. Therefore remember at all times that you are a child of the great King and it is not befitting to act in a lowly and degrading manner.
Everyone suffers. But many do not take it to heart that the suffering comes as a punishment for transgressions, rather they consider it accidental. The proper attitude is that suffering is an atonement. With this realization a person appreciates that suffering in this world saves him suffering in the next.
