The ongoing aspect matters: the words are shaped by seasons and by new voices. Younglings add humming refrains learned from the brook. A wandering minstrel’s cadence may be folded into the chorus for a summer. Those changes are not mistakes but accretions; the Blessing lives because it can carry new meaning. Its power, then, is not only in the spell but in the practice — in the ritual of remembering that a promise was made and must be kept.
