“Not for the sake of the wife,” says Yajnavalkya in the Upanishad, “but for the sake of the Self is the wife dear to us.” This in the lower sense of the individual self is the hard fact behind the coloured and passionate professions of egoistic love; but in a higher sense it is the inner significance of that same love too which is not egoistic but divine. All true love and all sacrifice are in their essence Nature’s contradiction of the primary egoism and its separative error; it is her attempt to turn from a necessary first fragmentation towards a recovered oneness. … The law of sacrifice travels in Nature towards its culmination in this complete and unreserved self-giving; it awakens the consciousness of one common self in the giver and the object of the sacrifice. This culmination of sacrifice is the height even of human love and devotion when it tries to become divine; for there too the highest peak of love points into a heaven of complete mutual self-giving, its summit is the rapturous fusing of two souls into one.”
