Judah the Pious, a commentary on the prayer ‘Aleynu

The Creator places in the heart of the prophet a vision (hezyon), and the Creator governs that image (dimyon)… Within the image the Creator directs the image according to what He wills to do so that the prophet will know the supernal Mind (da‘at ‘elyon) and bow down to Him and believe in Him. Thus he is bowing down to the Creator. It is written, “And they saw the God of Israel and under His feet etc.” (Exod. 24-10). The Creator is in that very image, and governs the image in accordance with what He wills… and that image is not separate from the Creator, blessed be He.
