Let us return to the man and woman within sight of the upper branches of the pine as they lay supine on the green bank of the river taking their ease after happy exertions. The slight sound of their voluptuous sighs had died away down the breeze. The vibrations of their meeting flesh had gone abroad through the blue evening, with the beaded moisture evaporating from their skins, and the heating scents of awakened sex, to become part of the endless waves of ether set up by the motions of the stars, by the odorous love-excitements of birds and beasts and reptiles, by the pollen of seeding plants. Of course the embracing couple did not know it: they knew nothing of the movement of the Spheres and their Rivers of life, nor of their component cells nor of the uncounted tribes of germs living within their bodies. Yet at the very crisis of the amorous passion the infinitely small no doubt bear their part in it to some degree, just as the lovers in their act have contributed to the harmony of the universe. We must try to think of ourselves existing as it were detached, hanging between an external medley of forces beyond our ken, and an internal current of life equally inappreciable by our senses. We seem to become sensitive to exterior sensation only locally, in the parts immediately affected. When lovers kiss the delight of it attacks mouth and heart and spirit alone. We never think that our arms or shoulders may also be concerned. Yet on reflection it would seem incontestable that the mere localization of the conscious emotion cannot prevent its being shared generally by our whole being. The kiss, though expressed only by our lips, is a product of the vitality of all our organs: and likewise in each of our actions we, from our tiny sector of the world, share in the universal harmony, though we cannot know the extent of our contribution nor trace its course through the clash of external forces.
