245. The objection can be raised to what has been proved above, that the soul is still propagated from the father, even though it is not linked to the mother's soul, even, in fact, though there is coldness lodged there which causes separation. But the reason souls or offspring are none the less propagated is because the man's intellect is not shut off, so as to prevent it being raised into the light enjoyed by the soul. But the love of his will is not raised into the heat corresponding to the light there, except by the way he lives; this is what makes him spiritual instead of natural. This is how it is that the soul is procreated, but wrapped up as it comes down to become sperm by the kind of things which have to do with his natural love. It is from this source that hereditary evil wells up.
To this I shall add a secret I have been told from heaven, that between the unlinked souls of the two, especially if they are married, a linking takes place in the middle of making love; and but for this the conception of human beings could not occur. See in addition what is said about coldness in marriage, and its location in the highest region of the mind, in the last account of experiences in this chapter (270).
