זוהר שמות — דף רנט ע”א

The lower world ascends to the upper world, hides within it and is revealed in the secret. The word olam (world) expresses this ascension and concealment. Jacob is above and Joseph below, two desires in two palaces: the sixth and the seventh. One who prolongs where one should be brief comes to heartache. The upper world ascends and hides in the highest degree, which contains seven supernal palaces and seven thousand lights.
