Our sages said, “An uneducated man, the fear of Shabbat is upon him.” A wise disciple is considered Shabbat, and Shabbat is considered Gmar Tikkun (the end of correction). Thus, as in Gmar Tikkun, the Kelim (vessels) will be corrected and fit to dress the Upper Light. Also, Shabbat is considered “end.” This means that the Upper Light can appear and clothe in the lower ones, but this is only considered an awakening from below.
