Arcana Coelestia #8
8. The second state is when a distinction is made between the things that are the Lord's and those that are man's own. Those which are the Lord's are called in the Word 'remnants', and here they are chiefly the cognitions of faith which a person has learned since he was a small child. These are stored away and do not come out into the open until he reaches this state. Nowadays this state rarely occurs without temptation, misfortune, and sorrow, which lead to the inactivity and so to speak the death of bodily and worldly concerns - the things which are man's own. In this way what belongs to the external man is segregated from what belongs to the internal. Within the internal are the remnants, stored away by the Lord until this time and for this purpose.

5812. 'The boy cannot leave his father' means that that truth cannot be separated from spiritual good. This is clear from the meaning of 'leaving' as being separated; from the representation of 'Israel' as spiritual good from the natural, dealt with in 4286, 4598, 5807; and from the representation of 'Benjamin' as new truth, dealt with in 5804, 5806. This truth is called 'the boy' because it is born last; for this truth is not born until a person has become regenerate. At this point he receives newness of life through this new truth joined to good, which also is why this truth is meant by 'a child of his old age, the youngest one', 5804.
