The heat and light that proceed from the Lord as a sun are what in an eminent sense are called the spiritual, and they are called the 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.
