I heard the following from R. Michoel Dvorkin:
Once in the time of the Sebastopol War5 the chassidim were sitting together with the Rebbe’s son, R. Chaim Shneur Zalman (the Rebbe of Liadi), when the Tzemach Tzedek walked in. It was a Heavenly decree, they were saying, the third army conscription in a single year — it’s surely time for Moshiach!
“We do not know darkness, ” the Tzemach Tzedek said. “We know only light. And as to the light that will be revealed when Moshiach comes — who knows what sort of darkness will have to precede such a light?”
