'v'raita es achorai, upanai lo yerau'.
"And I will take away my hand, and you shall see my back parts: but my face shall not be seen." (Exodus 33:23)
We humans can not know Him. We can only know who / what He is not.
And we are commanded to emulate Him & 'follow in His ways'...
I'll tell you one thing: I'm not who you think!
