Here are some excerpts from Swedenborg's "Arcana Coelestia" that help explain the inner meaning of this chapter:

AC 73. When from being dead a man has become spiritual, then from spiritual he becomes celestial, as is now treated of (verse 1).

AC 74. The celestial man is the seventh day, on which the Lord rests (verses 2, 3).

AC 75. His knowledge and his rationality (scientificum et rationale ejus) are described by the shrub and the herb out of the ground watered by the mist (verses 5, 6).

AC 76. His life is described by the breathing into him of the breath of lives (verse 7).

AC 77. Afterwards his intelligence is described by the garden in Eden, in the east; in which the trees pleasant to the sight are perceptions of truth, and the trees good for food are perceptions of good. Love is meant by the tree of lives, faith by the tree of knowledge (scientiae) (verses 8, 9).

AC 78. Wisdom is meant by the river in the garden. From thence were four rivers, the first of which is good and truth; the second is the knowledge (cognitio) of all things of good and truth, or of love and faith. These are of the internal man. The third is reason, and the fourth is memory-knowledge (scientia), which are of the external man. All are from wisdom, and this is from love and faith in the Lord (verses 10-14).

AC 79. The celestial man is such a garden. But as the garden is the Lord‘s, it is permitted this man to enjoy all these things, and yet not to possess them as his own (verse 15).

AC 80. He is also permitted to acquire a knowledge of what is good and true by means of every perception from the Lord, but he must not do so from himself and the world, nor search into the mysteries of faith by means of the things of sense and of memory-knowledge (sensualia et scientifica); which would cause the death of his celestial nature (verses 16, 17).

AC 131. The posterity of the Most Ancient Church, which inclined to their Own, is here treated of.

AC 132. Since man is such as not to be content to be led by the Lord, but desires to be led also by himself and the world, or by his Own, therefore the Own which was granted him is here treated of (verse 18).

AC 133. And first it is given him to know the affections of good and the knowledges of truth with which he is endowed by the Lord; but still he inclines to his Own (verses 19, 20).

AC 134. Wherefore he is let into a state of his Own, and an Own is given him, which is described by the rib built into a woman (verses 21 to 23).

AC 135. Celestial and spiritual life are adjoined to the man’s Own, so that they appear as a one (verse 24).

AC 136. And innocence from the Lord is insinuated into this Own, so that it still might not be unacceptable (verse 25).

78. Wisdom is described by 'the river in the garden', from which came 'four rivers'. The first of these is good and truth; the second is the knowledge of all things constituting good and truth, that is, constituting love and faith, which belong to the internal man; the third is reason, and the fourth knowledge, which belong to the external man. All of these derive from wisdom, which in turn stems from love to the Lord and faith in Him, verses 10-14.
