Different sides of time There's an invisible side of time, perceivable only by a sensitive soul. On the one hand, time flows swiftly like a river, carrying humans endlessly toward the future. But on the other hand, time can slow down, as if trapped in a moment of longing when the heart is drowning in longing, waiting, or loss. Time itself—some are trapped in the past, some run toward the future, and still others choose to remain somewhere in between.
