Jewish Mysticism
In the place that He makes His glory appear there He desires the intention of the one who prays; thus one must set a fixed place for one’s prayers. When a person worships in the place where His glory is, and the Creator is in His glory and governs it according to His will to inform the prophet of the will of the Creator, and he worships it, he believes in the Creator… Within the image (dimyon) is the Creator who governs it. “They saw the God of Israel” (Exod. 24-10) and worshipped Him, the Creator within the image, “and through the prophets I was imaged” (Hosea 12-11).
