spiritual in the singular number, because they are one; when, therefore,
the spiritual is mentioned in the following pages, it is meant both
these together. From that spiritual it is that the whole of that world
is called spiritual. Through that spiritual, all things of that world
derive their origin, and also their name. That heat and that light are
called the spiritual, because God is called Spirit, and God as Spirit
is the spiritual going forth. God, by virtue of His own very Essence,
is called Jehovah; but by means of that going forth He Vivifies and
enlightens angels of heaven and men of the church. Consequently,
vivification and enlightenment are said to be effected by the Spirit
of Jehovah.

Lord as a Sun, make one, may be illustrated by the heat and light that
go forth from the sun of the natural world. These two also make one in
their going out from that sun. That they do not make one on earth is
owing not to the sun, but to the earth. For the earth revolves daily
round its axis, and has a yearly motion following the ecliptic, which
gives the appearance that heat and light do not make one. For in the
middle of summer there is more of heat than of light, and in the middle
of winter more of light than of heat. In the spiritual world it is the
same, except that there is in that world no daily or yearly motion of
the earth; but the angels turn themselves, some more, some less, to the
Lord; those who turn themselves more, receive more from heat and less
from light, and those who turn themselves less to the Lord receive more
from light and less from heat. From this it is that the heavens, which
consist of angels, are divided into two kingdoms, one called celestial,
the other spiritual. The celestial angels receive more from heat, and
the spiritual angels more from light. Moreover, the lands they inhabit
vary in appearance according to their reception of heat and light. If
