What is Sheker? שקר Sheker is lies, deceipt. Even the letters are out of order from their correct listing in the alef bet [ק-ר-ש].
“And that’s how Moshiach is going to be revealed. Moshiach needs to be revealed from the epitome of sheker, Moshiach and his people. They’re not going to be pulled by the sheker. The sheker wants to take everyone. The sheker says: ‘I didn’t say enough sheker. Maybe I’ll say a little bit more, maybe I’ll succeed in saying something else, a different way.’ - “The more falsehood there is, the more truth will be revealed in a clearer way”
These days you need to search very hard to find your own truth. There is an abundance of Rabbis Impeding the Redemption. There is an abundance of sheker.
I heard from my teacher and father-in-law, who was the chief disciple of Rebbe Yechiel Michal of Zlotchov, that once when the Baal Shem Tov was traveling on the road, he stepped into a wooded area to pray the afternoon prayer. His disciples were dumbfounded to see him hitting his head against a tree, crying and screaming. Afterward, they asked him what had happened. He explained that he had seen, with divine inspiration, that in the generations before the coming of the Moshiach there would be a multitude of rabbis, and that they would be the very ones who would impede the redemption.
