HH 292-293 , 297 - conjunction with the spiritual world

HH 292
With every individual there are good spirits and evil spirits.
Through good spirits a person 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.

These spirits have no knowledge whatever that they are with a person . . ..
The Lord exercises the greatest care
that spirits may not know that they are with a person;
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 a person,
not alone his soul, that is, his faith and love, but also his body.

HH 293
. . . so far as a person's life is from what he inherits, and thus from self,
if he were not permitted to be in evil he would have no life;
also if he were not in freedom he would have no life;
also that he cannot be forced to what is good,
and that what is forced does not abide;
also that the good that a person receives in freedom
is implanted in his will and becomes as it were his own.
These are the reasons why a person has communication with hell
and communication with heaven.

HH 297
As to what further concerns the conjunction of heaven with the human race,
let it be noted that the Lord Himself flows into each person,
in accord with the order of heaven,
both into his inmosts and into his outmosts,
and arranges him for receiving heaven,
and governs his outmosts from his inmosts,
and at the same time his inmosts from his outmosts,
thus holding in connection each thing and all things in a person.
This influx of the Lord is called direct influx;
while the other influx that is effected through spirits is called mediate influx.
The latter is maintained by means of the former.
Direct influx, which is that of the Lord Himself,
is from His Divine Human,
and is into a person's will
and through his will
into his understanding,
and thus into his good
and through his good
into his truth,
or what is the same thing,
into his love
and through his love
into his faith;
and not the reverse,
still less is it into faith apart from love
or into truth apart from good
or into understanding that is not from will.
This Divine influx is unceasing,
and in the good is received in good,
but not in the evil;
for in them it is either rejected or suffocated or perverted;
and in consequence they have an evil life
which in a spiritual sense is death.
