from
them.

75. Spirits there speak with man, but man in his turn does not speak
with the spirits, except the words, when instructed, _that he will
do so no more_. Nor is he allowed to tell any one that a spirit has
spoken to him; if he does so, he is punished afterwards. Those spirits
of Jupiter, when they were with me, at first supposed that they were
with a man of their own earth; but when I in my turn spoke with them,
and also when I thought of publishing what passed between us, and so
relating it to others, then, because they were not allowed to chastise
or instruct me, they discovered that they were with a stranger.

76. There are two signs which appear to those spirits when they are
with man (_homo_). They see an old man (_vir_) with a white face; this
is a sign to speak only what is true, and to do only what is just.
They also see a face in a window; this is a sign to them to depart.
This old man has also appeared to me; and a face has also appeared in
a window, on seeing which those spirits immediately departed from me.

77. Besides the spirits who have already been mentioned, there are
spirits who urge contrary things. They consist of those who, during
their life in the world, had been banished from the society of others
because they were evil. When they approach there appears as it were
a flying fire, which descends near the face. They place themselves
beneath at the posterior parts of the man, and from thence they speak
towards the higher parts. They say things that are contrary to what
the instructor-spirit teaches from the angels, namely, that men
should not live according to instruction, but according to their own
inclination, and in licentiousness, with other similar things. They
generally come after the other spirits have departed; but the people
there know who and what those spirits are, and therefore pay no
attention to them. Still, they learn in this way what evil is, and
thereby what good is; for by means of evil one learns what good is,
inasmuch as the quality of good is known from its opposite. Every
perception of a thing is according to reflection relative to its
differences from things that are contrary in various ways and degrees.

78. The chastising and instructing spirits do not come to those who
call themselves saints and mediatory lords, and who have been treated
of above (at no. 70), as they do to others on that earth, because
they do not suffer themselves to be instructed and are not
