Explanation:

All worldly items have dimensions of space and hence are not beyond space. If the items were beyond space, they would also be unimaginable. But all the items of the world are only imaginable. No imaginable item can be a simile to the unimaginable God. Hence, a complete simile for God is absent in this world. In fact even a simile among worldly items is never perfect in all aspects. Someone’s face is compared to the moon. The moon increases and decreases [1] in a month but a person’s face has no such increase and decrease. Even an imaginable item cannot be a perfect simile to another imaginable item in the world. Then how can you find a perfect simile for the unimaginable God among imaginable items? Of course, God enters into an imaginable item as His medium. In that case the medium itself is said to be God just as the live wire is said to be the electric current itself. Here also the medium is treated as God but actually the medium is not God directly.
