There is an extensive discussion of demons – which are seen as invisible creatures surrounding each of us “a thousand on one his left hand and ten thousand on his right” – and the magical potion for being able to actually see them.
But I love another image from this page: the idea that just as religious Jews wear t’fillin as a sign of binding ourselves to G-d, G-d wears t’fillin as a sign of binding to us! If ours has the Sh’ma (G-d is One) as our text, G-d’s t’fillin uses I Chronicles 17:21: And what one nation in the earth is like thy people Israel. . . As we make G-d unique, G-d makes us unique.
