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'.

1731. That 'he blessed him' means the enjoyment of celestial and spiritual things becomes clear from the meaning of 'blessing' as having the enjoyment of all goods, dealt with in 981, 1096. People who enjoy celestial and spiritual goods have the enjoyment of all goods, for it is from the celestial and spiritual that all goods of every description derive. The things contained in this verse announce and proclaim the conjunction of the Lord's Human Essence with His Divine Essence. The blessing itself implies it.
