It says that the correction of the world will take 6000 years, which is related to the six workdays of the week. We were given 6000 years in order to prepare spiritual vessels, desires, tools. The “seventh millennium” (Sabbath) begins at the end of the correction of the vessels, which means that it is the next degree, called the state of the end of correction (Gmar Tikkun).
The state of Sabbath or the seventh millennium is called “the similarity to the future world” (Mi Ein Olam HaBaah) since it isn’t the future world itself yet, and there are the 8th, the 9th and the 10th millennia that follow it, corresponding to the first three Sefirot (GAR).
But the Sabbath begins even before that, even before the end of the 6000 years. A state of Sabbath (the first ascent of the worlds that brings us additional Light) already begins in the “fifth hour of the sixth day,” that is, on Friday. Therefore, the entire sixth day (which means our 6th millennium) is already illuminated by the Sabbath.
The whole sixth day is called “Sabbath eve,” and so we are in a very special time now: it is the time of Sabbath eve. We already feel the movement and the changes that are starting in the world on Sabbath eve. We will have to go through the whole period that is left until the end of correction, and it seems very short. The Sabbath is very near and we will soon reach it.
