In general, men are driven by intellect and women by affections, and because of this men in the Bible generally represent knowledge and truth and women generally represent love and the desire for good. This generally carries over into marriage, where the man's growing knowledge and understanding and the woman's desire to be good and useful are a powerful combination. In many cases in the Bible, then, "husband" refers to things of truth and understanding, much as "man" does. Magnificent things can happen in a true marriage, though, when both partners are looking to the Lord. If a husband opens his heart to his wife, it's as though she can implant her loves inside him, transforming his intellectual urges into a love of growing wise. She in turn can grow in her love of that blooming wisdom, and use it for joy in their married life and in their caring for children and others in their life. Many couples, even in heaven, stay in that state -- called "Spiritual" -- growing deeper and deeper to eternity. There is the potential, though, for the couple to be transformed: through the nurturing love of his wife the husband can pass from a love of growing wise to an actual love of wisdom itself, and the wife can be transformed from the love of her husband's wisdom into the wisdom of that love -- the actual expression of the love of the Lord they have built together. In that state -- called "Celestial" -- the husband represents love and the desire for good, and the wife represents truth and knowledge.

Furthermore such is the correspondence of the brain with the Grand Man that those whose first intentions are directed to what is good correlate with those parts in the brain which are the first beginnings there and are called the glands or cortical substances. But those whose first intentions are directed to what is true correlate with those parts in the brains which emanate from those first beginnings and are called fibres. But the following distinction has to be made - those who correspond to the right side of the brain are those with whom the will for what is good and so for what is true predominates, whereas those who correspond to the left side of the brain are those with whom the understanding of what is good and true and so the affection for such predominates. The reason for this is that the good done by those in heaven who are on the Lord's right springs from the will, but the good done by those on the Lord's left springs from the understanding. The former are the ones who are called celestial, but the latter the ones who are called spiritual.
