2992. It has been given me to know from much experience that in the natural world and its three kingdoms there is nothing whatever that does not represent something in the spiritual world, or that has not something there to which it corresponds. Besides many other experiences, this was made evident also from the following. On several occasions when I was speaking of the viscera of the body, and was tracing their connection from those which are of the head to those which are of the chest, and so on to those which are of the abdomen, the angels that were above me led my thoughts through the spiritual things to which those viscera correspond, and this so that there was not the least error. They thought not at all of the viscera of the body of which I was thinking, but only of the spiritual things to which these correspond. Such is the intelligence of angels that from spiritual things they know all things in the body in general and particular, even the most secret things, such as can never come to man's knowledge; nay, they know everything there is in the universal world, without a mistake; and this because from spiritual things are the causes, and the beginnings of causes.
