[2] There are two sides to the internal man, namely the celestial and the spiritual, and these two form a single entity if the spiritual has its origin in the celestial. Or what amounts to the same, there are the two sides to the internal man known as good and truth. These two form a single entity if truth has its origin in good. Or what also amounts to the same, there are the two sides to the internal man, love and faith. These two form a single entity if faith has its origin in love. Or what yet again amounts to the same, there are the two sides to the internal man, will and understanding These two form a single entity if the understanding has its origin in the will. The light from the sun can serve to make the point plainer still. If both warmth and light are present in light from the sun, as they are in spring-time, all things consequently start to grow and thrive. But if, as in winter, there is no warmth in the light from the sun all things at that time consequently fade and die.

[3] From this it is clear what constitutes the internal man. What constitutes the external man however is evident from the fact that with the external man everything is natural; for the external man is one and the same as the natural man. The internal man is said to be united to the external when the celestial- spiritual comprising the internal man flows into the natural comprising the external man and causes them to act as one. The natural as a consequence becomes celestial and spiritual as well, though it is a lower variety of celestial and spiritual. Or what amounts to the same, the external man as a consequence becomes celestial and spiritual as well, though it is a more exterior variety of celestial and spiritual man.

[4] The internal man and the external man are completely distinct and separate since celestial and spiritual things are what move the internal man but natural things the external man But although they are distinct they are nevertheless united, that is to say, when the celestial-spiritual comprising the internal man flows into the natural comprising the external man and reorganizes it as its own. In none but the Lord has the Internal Man been united to the external Man. It has happened to nobody else except insofar as the Lord has united and does unite them. It is solely love and charity, that is, good, which effects union, and there can never be any love and charity, that is, any good, unless it comes from the Lord. Such is the union which these words of Abram are meant to convey- 'let there not be strife, now, between me and you, and between my herdsmen and your herdsmen, for we are men who are brothers'.

[5] The words 'between me and you, and between my herdsmen and your herdsmen' are used for the following reason: just as the internal man has two elements, namely the celestial and the spiritual which, as has been stated, form a single entity, so too does the external man. The celestial side of the external man is called natural good, the spiritual side natural truth. 'Let there not be strife between me and you' has regard to good - that is, let there be no conflict between good in the internal man and good in the external, while 'let there be no strife between my herdsmen and your herdsmen' has regard to truth - that is, let there be no conflict between truth in the internal man and truth in the external.
