The charkha was a timer, not a symbol
Every morning, without exception, Gandhi sat at the charkha for at least thirty minutes. The spinning wheel produced khadi, yes, but the practice produced something else. Gandhi wrote in his autobiography, My Experiments with Truth, that the charkha taught him what no political meeting could: that undivided attention to a single, repetitive physical task quiets the part of the mind that generates noise. He was not meditating. He was working. The distinction matters.
