A bond of love like this is damaging after death, as we can see from the state of heaven, the state of hell, and the state of our spirit in relation to both.
The state of heaven is that it has been divided into countless communities according to all the different feelings of love for what is good. Hell on the other hand has been divided according to all the different feelings of love for what is evil.
After we die and become spirits, we are immediately attached to the community that shares our dominant love, based on the way we lived in the world. This community is in heaven if love for God or for our neighbor was primary among all the things we love. We are assigned to a community of hell if love for ourselves for the world was primary among all the things we love.
After we have entered the spiritual world–which happens as a result of our dying and our physical body being laid to rest in the grave–we next spend a while being prepared for the community to which we have been assigned. This preparation is a matter of our rejecting things we love that do not agree with our primary love. During this same period of time, people are separated from each other–friends are separated, followers are separated from their leaders, parents are separated from their offspring, and siblings are separated from each other. Then we all become deeply attached to people similar to ourselves with whom we are going to live a life that is both shared and is truly our own to eternity.
During the first part of this preparation people meet and talk in a friendly way as they had in the world. Little by little, however, they are separated from each other. It happens without their realizing it.
