9301. Thou shalt not boil a kid in its mother's milk. That this signifies that the good of innocence of the after state must not be conjoined with the truth of innocence of the former state, is evident from the signification of "to boil," as being to conjoin (see n. 8496); from the signification of "a kid," as being the good of innocence (n. 3519, 4871); and from the signification of "milk," as being the truth of innocence (n. 2184, 3183); thus the "mother's milk" denotes the truth of the first innocence. From all this it is evident that by "thou shalt not boil a kid in its mother's milk" is signified that the good of innocence of the after state must not be conjoined with the truth of innocence of the former state. This is the heavenly secret from which this law emanates; for all the laws and judgments and statutes that were given to the sons of Israel, contain secrets of heaven, to which they also correspond. But how this secret is to be understood, namely, that the good of innocence of the after state must not be conjoined with the truth of innocence of the former state, shall be briefly stated. The innocence of the former state is the innocence of infants and children; and the innocence of the after state is the innocence of adults and the aged who are in the good of love to the Lord. The innocence of infants and children is external, and dwells in dense ignorance; but the innocence of the aged is internal, and dwells in wisdom. (Concerning the difference between these two, see n. 2305, 2306, 3183, 3994, 4797.)
[2] The innocence that dwells in wisdom consists in the man's knowing, acknowledging, and believing that he can understand nothing and will nothing from himself, and consequently in his not wishing to understand and will anything from himself, but only from the Lord; and also that whatever he supposes that he understands from himself is falsity; and whatever he supposes that he wills from himself is evil. This state of life is the state of innocence of the after state, in which are all who are in the third heaven, which is called "the heaven of innocence." Hence it is that such are in wisdom, because all they understand and will is from the Lord. But the innocence which dwells in ignorance, such as exists with infants and children, consists in believing that all they know and think, and also all they will is in themselves; and that all they speak and do from this thought and will is from themselves. That these are fallacies, they do not apprehend. The truths belonging to this innocence are for the most part founded upon the fallacies of the external senses; and these fallacies must be shaken off as the man advances toward wisdom. From these few words it can be seen that the good of innocence of the after state must not be conjoined with the truth of innocence of the former state.
