Quarreling over food and drink, having neither scruples nor shame, not knowing right from wrong, not trying to avoid death or injury, not fearful of greater strength or of greater numbers, greedily aware only of food and drink - such is the bravery of the dog and boar.

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

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.

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

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