Marriage #35
35. (to) A wife wishes to think and will what her husband does, and a husband what his wife does, and because each wishes this, each is led by the Lord as if they were one, and the two are a single angel. For when one's will and understanding is not one's own, but another's, and this is mutually so in turn, they cannot but be led by the Lord as if one.
Arcana Coelestia #3504
3504.'So that my soul may bless you' means allying it to its own life, consequently life that corresponds to the rational. This is clear from the meaning of 'being blessed' as being endowed with celestial and spiritual good, dealt with in 981, 1731, 2846, 3017, 3406. For the good of early childhood and consequently the good of life, which is the same as the good of the natural, and which is represented by 'Esau', is not spiritual good, for the good of early childhood is devoid of knowledge and intelligence, and so of wisdom. The good of early childhood becomes spiritual good through the implantation of truth, and so through regeneration, see 1616, 1802, 2280, 2290, 2291, 2299, 2304, 2305, 2307, 3494 (end). This is how the correspondence between rational things and natural is effected, and so how the allying of the natural man to the life of the rational is effected. This allying to its own life is what is meant by 'my soul may bless you'.
