זוהר שמות — דף רכב ע”ב

Beautiful in its heights, joy of all the earth, Mount Zion. The Holy One, blessed be He, cast a precious stone from beneath His throne of glory and plunged it to the abyss, and its uppermost point is the central point of the world. This stone is the Shethiya — foundation of the world, Shat Yah. The Temple is the first expansion surrounding that central point, with Jerusalem and all the city facing it as a center. When the Ark entered the Holy of Holies, the world was rectified and the Name declared: This is My resting place forever, here I will dwell for I have desired it.
