CL 194, 200 - putting aside inherent natures and becoming truly human

CL 194
. . . it was enjoined on man that he leave father and mother
and cling to his wife(Genesis 2:24, Matthew 19:4,5).
[2] The father and mother a man is to leave mean,
in a spiritual sense,
the inherent nature of his will
and the inherent nature of his intellect
(the inherent nature of a person's will
being to love itself,
and the inherent nature of a person's intellect
being to love its own wisdom).
And to cling means to commit himself to love of his wife.
These two inherent natures are evil and deadly to a man
if they remain in him,
but the love arising from the two is turned into conjugial love
as a man clings to his wife, that is, as he acquires a love for her.

CL 200
. . . in a marriage of truly conjugial love,
each partner becomes more and more deeply human,
for that love opens the deeper aspects of their minds,
and as these are opened,
a person becomes more and more human.
