292. With every individual there are good spirits and evil spirits. Through good spirits man has conjunction with heaven, and through evil spirits with hell. These spirits are in the world of spirits, which lies midway between heaven and hell. This world will be described particularly hereafter. When these spirits come to a man they enter into his entire memory, and thus into his entire thought, evil spirits into the evil things of his memory and thought, and good spirits into the good things of his memory and thought. These spirits have no knowledge whatever that they are with man; but when they are with him they believe that all things of his memory and thought are their own; neither do they see the man, because nothing that is in our solar world falls into their sight.{1} The Lord exercises the greatest care that spirits may not know that they are with man; for if they knew it they would talk with him, and in that case evil spirits would destroy him; for evil spirits, being joined with hell, desire nothing so much as to destroy man, not alone his soul, that is, his faith and love, but also his body. It is otherwise when spirits do not talk with man, in which case they are not aware that what they are thinking and also what they are saying among themselves is from man; for although it is from man that they talk with one another, they believe that what they are thinking and saying is their own, and everyone esteems and loves what is their own. In this way spirits are constrained to love and esteem man, although they do not know it. That such is the conjunction of spirits with man has become so well known to me from a continual experience of many years that nothing is better known to me. {Footnote 1} There are angels and spirits with every man, and by means of them man has communication with the spiritual world (n. 697, 2796, 2886, 2887, 4047, 4048, 5846-5866, 5976-5993). Man without spirits attending him cannot live (n. 5993). Man is not seen by spirits, even as spirits are not seen by man (n. 5862). Spirits can see nothing in our solar world pertaining to any man except the one with whom they are speaking (n. 1880).
