The conception and its existence are two sides, distinct yet united, like soul and body. The body is the same life as the soul, and yet the two can be named independently. A soul without a body would not be a living thing, and vice versa. Thus the visible existence of the conception is its body, just as the body obeys the soul which produced it.
The body is amazingly plastic. The spirit, even more so. But there are some things you don’t come back from. Say ye so, a nighean? True, the body’s easily maimed, and the spirit can be crippled—yet there’s that in a man that is never destroyed.
