215. (5) People who are in a state of truly conjugial love continually wish to be one person, but those who are not in a state of conjugial love want to be two separate individuals. Conjugial love in its essence is nothing else but the wish of two to be one, or, in other words, a will on their part that their two lives become one life. To carry out that will is the constant endeavor of this love, and all that it does flows from it. It has been established from the investigations of philosophers, and it is also evident to people of educated reason who reflect, that effort is the very essence of motion, and that will in the human being is a living effort. It follows from this that people who are in a state of truly conjugial love continually have within them an effort, or will, to be one person. That the opposite is the case with those who are not in a state of conjugial love, they themselves very well know. For they constantly think of themselves as two separate individuals, owing to a lack of union between their souls and minds, and they therefore do not see what is meant by the Lord's words, that "they are no longer two but one flesh" (Matthew 19:6).
