Man can't make a relationship by himself. The word "relationship" can make sense only when there is a condition, which requires a reciprocative object. A condition of reciprocity is the condition for subject and object forming a reciprocal relationship. In order for a subject and an object partner to establish a reciprocal relationship, they should have something in common. Without it, they can't make it.

When you want something, you surely want something better than what you have at the moment. So both a subject and an object are going forward together, pursuing something better in common. We can't speak of a condition of reciprocity without speaking of a subject and an object. Then they engage in giving and receiving. In giving and receiving, giving is more valuable than receiving. They are doing so because they have some greater purpose. Nobody gives or receives something in order to damage himself.

The reason that parents love their children is not because parents want some reward for doing so, but because they want to love the children on a higher spiritual level in every way. Then, what is the purpose for parents to love their children? They love their children not because they expect anything in reward for doing so, but because they hope to reach a greater standard and goal of life.

For this reason, parents not only love their children but also they hope that their children will be those who are needed by the people, the nation, the world and a greater being, as well as by the parents themselves. Parents do not love their children for the sake of the parents themselves but for the sake of something greater. That is parents' love toward their children. (49-180)
