Therefore, a person should first be changed by a teacher's instructions, and guided by principles of ritual. Only then can he observe the rules of courtesy and humility, obey the conventions and rules of society, and achieve order.

When people lack teachers, their tendencies are not corrected; when they do not have ritual and moral principles, then their lawlessness is not controlled.

A person is born with desires of the eyes and ears, and a liking for beautiful sights and sounds. If he gives way to them, they will lead him to immorality and lack of restriction, and any ritual principles and propriety will be abandoned.

Thus, anybody who follows this nature and gives way its states will be led into quarrels and conflicts, and go against the conventions and rules of society, and will end up a criminal.

Since the nature of people is bad, to become corrected they must be taught by teachers and to be orderly they must acquire ritual and moral principles.

In order to properly understand the big picture, everyone should fear becoming mentally clouded and obsessed with one small section of truth.
