According to Osho, a single insight dissolves the past without repression: realize that only the present is real—past is memory, future imagination. When you rest in thought-free awareness (meditation), you tune to “that which is,” and the past and future drop by themselves, like darkness vanishing when a candle is lit—instant, effortless, liberating satori.
See that only now is real; when you stop chasing thoughts about before or later, they fade on their own.
