ANGELS talk with each other just the way we do in this world. They talk about various things—domestic matters, community concerns, issues of moral life, and issues of spiritual life. There is no difference except that they talk with each other more intelligently than we do because they talk from a deeper level of thought.
I have often been allowed to be in their company and talk with them like one friend with another, or sometimes like one stranger with another; and since at such times I was in a state like theirs, it seemed exactly as though I were talking with people on earth.
