The poster sentence is a modern condensation associated with Gandhi. The evidence trail points instead to a longer passage in Gandhi's writing; the exact compact wording is not treated as a Gandhi quotation here.
Gandhi's closest traceable passage is a longer discussion of changing oneself and the world's response, not this compact sentence.
Earliest traceable appearance in this record: The exact wording is not established in the cited evidence; the closest Gandhi passage is reported by The New York Times.
