The lover is moved by the beloved object as the senses are by
sensible objects; and they unite and become one and the same thing.
The work is the first thing born of this union; if the thing loved
is base the lover becomes base.

When the thing taken into union is perfectly adapted to that which
receives it, the result is delight and pleasure and satisfaction.

When that which loves is united to the thing beloved it can rest
there; when the burden is laid down it finds rest there.
