The person attempting to travel two roads at once will get nowhere.

I once tried thinking for an entire day, but I found it less valuable than one moment of study.

A person is born with feelings of envy and hate. If he gives way to them, they will lead him to violence and crime, and any sense of loyalty and good faith will be abandoned.

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.

Those whose character is mean and vicious will rouse others to animosity against them.

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.
