Love tends to union (St. Francis de Sales)

   As love tends to union, even so very often union extends and augments love: for love makes us seek the society of the beloved, and this often nourishes and increases love; love causes a desire of nuptial union, and this union reciprocally preserves and increases love, so that in every sense it is true that love tends to union. But to what kind of union does it tend? Did you not note, Theotimus, that the sacred spouse expressed her desire of being united to her spouse by the kiss, and that the kiss represents the spiritual union which is caused by the reciprocal communication of souls? It is indeed the man who loves, but he loves by his will, and therefore the end of his love is of the nature of his will: but his will is spiritual, and consequently the union which love aims at is spiritual also, and so much the more because the heart is the seat and source of love.
