Here now they say, 'If (the dviyagus) is that same Sacrificer who is that gold man, which then is that (real) form of his?' Well, that (gold man) is his divine body, and this (brick) is his human one. As to that gold man, that is his immortal form, his divine form; gold being immortal. And as to this (brick) being made of clay, it is because this is his human form.
