9301. 'You shall not cook a kid in its mother's milk' means that the good of innocence belonging to a later state must not be joined to the truth of innocence belonging to an earlier state. This is clear from the meaning of 'cooking' as joining together, dealt with in 8496; from the meaning of 'a kid' as the good of innocence, dealt with in 3519, 4871; and from the meaning of 'milk' as the truth of innocence, dealt with in 2184, 3183, so that 'mother's milk' is the truth of earlier innocence. From these meanings it is evident that 'you shall not cook a kid in its mother's milk' means that the good of innocence of a later state must not be joined to the truth of innocence of an earlier state. This is the heavenly arcanum from which that law springs; for all the laws and all the judgements and statutes which were given to the children of Israel contain heavenly arcana, to which they also correspond. But how this arcanum should be understood - that the good of innocence belonging to a later state must not be joined to the truth of innocence belonging to an earlier state - must be stated briefly. The innocence belonging to an earlier state is the innocence that exists with young children and older ones, but the innocence belonging to a later state is the innocence that exists with grown up and elderly people who are governed by the good of love to the Lord. The innocence that exists with young children and older ones is external and resides in thorough ignorance, whereas the innocence of elderly people is internal and resides in wisdom. Regarding the difference between the two, see 2305, 2306, 3183, 3494,a 4797.
[2] The innocence which resides in wisdom consists in a person's knowing, acknowledging, and believing that all by himself he cannot understand anything at all or will anything at all, and therefore in his refusal to try and understand or will anything all by himself, only in the power of the Lord; and also this, that whatever he thinks he understands all by himself is false, and whatever he thinks he wills all by himself is evil. This state of life is that of the innocence of a later state, which is that of all in the third heaven, called the heaven of innocence. This is why they are filled with wisdom, for what they understand and what they will comes from the Lord. But the innocence which resides in ignorance, such as that present with young children and older ones, consists in believing that everything they know and think, and also everything they will, is theirs within them, and that therefore everything they say and do comes from themselves. They have no idea that these are illusions. The truths that go with this innocence are based for the most part on the illusions of the outward senses, which however must be dispelled as a person advances towards wisdom. From this brief explanation it may be recognized that the good of innocence belonging to a later state must not be joined to the truth of innocence belonging to an earlier state.
