A mother’s love! O holy, boundless thing! Fountain whose waters never cease to spring!

The exclamation frames maternal love as a sacred, inexhaustible force—“holy” in moral stature and “boundless” in scope. By likening it to a perpetually springing fountain, the speaker emphasizes constancy and renewal: a mother’s care is imagined not as a finite resource but as something that replenishes itself even as it is given away. The heightened diction and apostrophe (“O”) place the sentiment in a devotional register, suggesting reverence rather than mere affection. The couplet’s rhythm and imagery also align with a long literary tradition that idealizes motherhood as both nurturing and spiritually elevating, turning private emotion into a universal emblem of selfless generosity.
