Arcana Coelestia #35
35. Man has two inherent powers of will and understanding. When the understanding is governed by the will they then constitute one mind and so one life; for what a person in that case wills and does he also thinks and intends. But when the understanding is at variance with the will, as it is with people who claim to have faith and yet live otherwise, then a mind previously one is split in two. One half seeks to transport itself into heaven, while the other inclines towards hell. And because the will is what accomplishes everything, the whole man would rush straight into hell unless the Lord took pity on him.

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.
