It is not quite right to say, “Beauty will save the world”; it is more precise to say, “Awareness of beauty will save the world.”
You can pass through the obstacles of ugliness on the way to the lighthouse of beauty, scattering seeds without number. When one is able to create a garden of beauty, there is nothing to fear. When the garden of the spirit admits the newcomers, there is no fatigue. (NEC (opens in new tab), 27)
