Rather we would like to describe an orbit as large as the earth's movement around the sun. In a family, children will be proud that they have been loved by their grandparents as well as their parents. The more love we receive, not only from our parents, the more we like it. If we can receive the love of all generations back to the origin of mankind that is ideal. We want eternal love.
Life is a static thing.
If life were our ideal those who lived longer would always be over us. There would be a hierarchy of age. But in love everything is dynamic. I can be the subject of my grandparents. The positions are flexible and dynamic.
