HaLeiVi:
Just realize, all the Mefarshey Rashi deal with these Rashi’s without batting an eyelash. Whatever it means it means. It’s not the first funny sounding Medrash. The fact is that Yecheskiel Hanavi saw KiDmus Mar’eh (which is three stages of comparison). There is a form to speak of, and it doesn’t mean that you are defining Hashem with that.
The best way that I can explain this (and I really do mean it) is “second sight”. Meaning, when someone “sees” something that their mind can’t comprehend (and that is what a Nevuah is, “seeing”), the mind tries to translate it into something that it can comprehend, and moves past the original “first sight”. This may be what a Human mind can comprehend (a form), and may even be how us Humans relate to the Ribbono Shel Olam, but in no way is that the actuality of the Ribbono Shel Olam.
