Part 1 (Sections 1-82) explains how divine love and wisdom form a single whole in the Lord. Warmth and light form a similar whole because they are emanations, and emanations constitute a whole by reason of their correspondence. The warmth answers to love, and the light to wisdom.
It therefore follows that since divine love is the divine reality and divine wisdom is the divine manifestation (see Sections 14–16 above), spiritual warmth is Divinity emanating from the divine reality and spiritual light is Divinity emanating from the divine manifestation. This means that just as divine love is a property of divine wisdom and divine wisdom is a property of divine love because of this union (see Sections 34–39 above), spiritual warmth is a property of spiritual light and spiritual light is a property of spiritual warmth. As a result of this kind of oneness, it follows that warmth and light are a single whole as they emanate from the Lord as the sun.
We will see later, though [Section 125], that they are not accepted as a single whole by angels or by us.
The warmth and light that emanate from the Lord as the sun are what we call “spiritual”; and they are referred to as spiritual in the singular because they are a single whole. In the following pages, therefore, when it says “spiritual” it will mean both as a single whole. It is because of this spiritual [energy] that the whole other world is called “spiritual.” Everything in that world has its source in that spiritual [energy] and takes its name from it as well.
The reason the warmth and light are called “spiritual” is that God is called “the Spirit,” and God as the Spirit is that emanation. As to his very essence, God is called Jehovah; but he enlightens and gives life to heaven’s angels and to us of the church through that emanation. This is why it is said that giving life and bringing about enlightenment are acts performed by the spirit of Jehovah.
