And of truth in the same degree?

Yes.

And, conversely, that which has less of truth will also have less of essence?

Necessarily.

Then, in general, those kinds of things which are in the service of the body have less of truth and essence than those which are in the service of the soul?

Far less.

And has not the body itself less of truth and essence than the soul?

Yes.

What is filled with more real existence, and actually has a more real existence, is more really filled than that which is filled with less real existence and is less real?

Of course.
