By a spiritual vision I was shown today that we are not acquainted with even the most general of facts in heaven. Take, for example, the fact that only one point of thought that we regard as most subtle and complete, contains within it, so to speak, the whole of heaven. For there is something in heaven residing in every least particle. This seems amazing, to be sure, and yet it is just as in each least part of a human being, there is a communication of every least thing that is going on in the [whole] body. 1748, 23 April.
