Affection as the essential principle of relatedness is of the greatest importance in all relationships in the world. For the union of heaven and earth is the origin of the whole of nature. Among human beings likewise, spontaneous affection is the all-inclusive principle of union.
Every relationship between individuals bears within it the danger that wrong turns may be taken, leading to endless misunderstandings and disagreements. Therefore it is necessary constantly to remain mindful of the end. If we permit ourselves to drift along, we come together and are parted again as the day may determine. If on the other hand a man fixes his mind on an end that endures, he will succeed in avoiding the reefs that confront the closer relationships of people.
