[2] There are two things in the internal man, namely, the celestial and the spiritual, which two constitute a one when the spiritual is from the celestial; or what is the same, there are two things in the internal man, good and truth; these two constitute a one when the truth is from good; or what is also the same, there are two things in the internal man, love and faith; these two constitute a one when the faith is from love; or what is again the same, there are in the internal man two things, the will and the understanding; and these two constitute a one when the understanding is from the will. This may be apprehended still more clearly by considering the sun, from which is light. If in the light from the sun there are both heat and illuminating power, as in the spring-time, all things are thereby made to vegetate and to live; but if there is not heat from the sun in the light, as in the time of winter, then all things become torpid and die.

[3] From all this it is evident what constitutes the internal man; and what constitutes the external thence appears. In the external man all is natural; for the external man itself is the same as the natural man. The internal man is said to be united to the external when the celestial spiritual of the internal man flows into the natural of the external, and makes them act as a one. As a consequence of this the natural also becomes celestial and spiritual, but a lower celestial and spiritual; or what is the same, the external man becomes celestial and spiritual, but a more external celestial and spiritual.

[4] The internal man and the external are altogether distinct, because celestial and spiritual things are what affect the internal man, but natural things are what affect the external. But though distinct, they are still united, namely, when the celestial spiritual of the internal man flows into the natural of the external, and disposes it as its own. In the Lord alone the internal man was united to the external; this is not the case in any other man, except so far as the Lord has united and does unite them. Love and charity only, or good, is what unites; and there is never any love and charity, that is, any good, except from the Lord. Such is the union that is intended in these words of Abram: "Let there be no contention between me and thee, and between my herdmen and thy herdmen."

[5] It is said, "Between me and thee, and between my herdmen and thy herdmen," for the case is thus as there are two things in the internal man, namely, the celestial and the spiritual, which as before said make a one, so also are there in the external man, its celestial being called natural good, and its spiritual natural truth. "Let there be no contention between me and thee," has reference to good, meaning that the good of the internal man should not disagree with the good of the external man; and "Let there be no contention between my herdmen and thy herdmen," has reference to truth, meaning that the truth of the internal man should not disagree with the truth of the external man.
