1475. 'Say, now, you are my sister' means intellectual truth, which is 'a sister'. This becomes clear from the meaning of 'sister' as intellectual truth when celestial truth is meant by 'wife', which meaning of 'sister' is shown further on. The implications here are as follows: Knowledge is of such a nature that it desires nothing more than to introduce itself into celestial things and examine them. But this is contrary to order, for if knowledge is used in this way it does violence to celestial things. The proper order is for the celestial to introduce itself by way of the spiritual into the rational and in this manner into factual knowledge, and to adapt this to itself. Unless this order is kept no wisdom can possibly exist. Also contained in the present section there are arcana as to how the Lord was taught by His Father according to order in its completeness, and so how His External Man was joined to His Internal - that is, how His external Man was made Divine, even as His Internal Man was essentially Divine, and so how He became Jehovah as regards both Essences This was accomplished by means of cognitions, which are the means. Without cognitions as means the external man cannot indeed become truly man.
