The prayer asks for peace while carrying unrest beneath its calm. The words ask the Casta Diva to turn an unveiled face toward the sacred trees, to temper burning hearts and excessive zeal, and to scatter on earth the peace that reigns in heaven.

Callas makes that contradiction feel lived. The line is suspended, spacious, and intensely controlled, with the orchestra and chorus widening the prayer into public ceremony while her voice keeps a human edge inside the purity. Nothing about the calm is empty; it sounds earned by force of will. Divinity here is not distance from feeling, but feeling held so completely that it can pass, for a moment, as peace.
