His grave a nation's heart shall be, His monument a people free!

The couplet frames an ideal of civic remembrance in which the truest memorial to a great figure is not stone or bronze but the living gratitude and liberty of the community. “His grave a nation’s heart” shifts burial from a physical site to collective feeling, suggesting that public memory and shared mourning are the real sepulcher. “His monument a people free” makes freedom the enduring tribute: the person’s legacy is measured by the continued flourishing of a free populace. The lines thus link commemoration to political and moral outcomes, implying that a life devoted to the common good is best honored by preserving the conditions—especially liberty—that the person helped secure.
