Unity to be real must stand the severest strain without breaking.

Gandhi’s line treats “unity” not as a slogan or temporary alignment of interests, but as a moral and practical bond that proves itself under pressure. Real solidarity, in this view, is measured when communities face fear, provocation, sacrifice, or disagreement—moments when opportunism and factionalism typically surface. The “severest strain” implies crises such as repression, communal tension, or political setbacks; if unity collapses then, it was only superficial. The statement also carries an ethical challenge: to build forms of cooperation grounded in truth, discipline, and mutual respect, so that unity can endure tests rather than depend on favorable circumstances.
