Yes the whole thing about the mouth is true but, some ppl had it rumored that sauron would stand against aragorn in the final moments of the film. All I was saying is that someone did bring up a good point. In the first war we see sauron wearing the ring....if he could just damage ppl by being a spirit...would'nt he have done that in the first place. If the "eye" is capable of wearing the ring why waste your time with a physical form?.
All I am saying is that he must have had some plan to PUT the ring back on so it would make sense to me that he had a body ready.
Sauron could not becom corporal without the ring. He was just energy. I think once the ring was back in his possession(part of his being) he would form a new body to go with the ring.
He could not have stood against Aragorn. Also he could only project his will not any real damage.
Much like many testaments about Satan.
