Love is an immortal wound that cannot be closed up. A person loses something, a part of her soul, when she loves someone. And she goes about looking for that lost part of her soul, for she knows that otherwise she is incomplete and cannot be at rest. It is only when she is with the person she loves that she becomes complete again in herself; but the moment he leaves, she loses that part which he has taken with him and knows no rest till she has found him once more.
