4644. CONCERNING HEAVEN WITH MAN. The communication of heaven with man is wonderful; and, unless one is instructed by the Lord, it can never be known, nor, if known, believed. Influx is rarely of such a kind that it falls into manifest thought; for this [that falls into manifest thought] comes from spirits who are near man - but influx is of the following character. With man are such things as he believes, and by which he is affected from the heart. When the angels who are with him are in such things, and speak together concerning them, then inflows with the man cheerfulness, contentment, and tranquillity of mind; but, when such things are not in the faith and affection of the man, then inflows sadness and disquiet, and similar things; and this influx no otherwise falls into the thought of the man - who may be thinking of quite another matter, at the time. Concerning this, I have been at length instructed by much experience; for I did not know whence was sadness, and whence cheerfulness of mind, when I was not thinking or speaking, of such things as occasion them - but I then perceived that the cause was thence.
