5978. That there are two angels with every man is because of these also there are two kinds, of which one act into what is of man's will, and the other into what is of his understanding. They who act into what is of man's will, act into his loves and ends, consequently into his goods. But they who act into what is of man's understanding, act into his faith and principles, consequently into his truths. These two kinds also are most distinct from each other. They who act into what is of man's will are called celestial, and they who act into what is of his understanding are called spiritual. To the celestial are opposed the genii, and to the spiritual the spirits. These things it has been given me to know by much experience, for I am continually in company and discourse with them both.
