concerning this Vision, that those separated Essences, if they chance to
be in Bodies of perpetual Duration, as the Heavenly Bodies are, shall
also remain perpetually, but if they be in a Body which is liable to
Corruption (such an one as belongs to us reasonable Creatures) that then
they must perish too, and vanish away, as appears from the Similitude of
the Looking-glasses which I have us'd to explain it; because the Image
there has no Duration of itself, but what depends upon the Duration of
the Looking-glass; and if you break the Glass, the Image is most
certainly destroy'd and vanishes. In answer to this I must tell you,
that you have soon forgot the Bargain I made with you. For did not I
tell you before that it was a narrow Field, and that we had but little
room for Explication; and that _Words_ however us'd, would most
certainly occasion Men to think otherwise of the thing than really it
was? Now that which has made you imagine this, is, because you thought
that the Similitude must answer the thing represented in every respect.
But that will not hold in any common Discourse; how much less in this,
where the Sun and its Light, and its Image, and the Representation of
it, and the Glasses, and the Forms which appear in them, are all of them
things which are inseparable from Body, and which cannot subsist but by
it and in it, and therefore the very Essences of them depend upon Body,
and they perish together with it.

§ 95. But as for the Divine Essences and Heroick Spirits, they are all
free from Body and all its Adherents, and remov'd from them at the
utmost distance, nor have they any Connection, or Dependance upon them.
And the existing or not existing of Body is all one to them, for their
sole Connection and Dependance is upon that ONE TRUE NECESSARY
SELF-EXISTENT BEING, who is the first of them, and the Beginning of
them, and the Cause of their Existence, and he perpetuates them and
continues them for ever; nor do they want the Bodies, but the Bodies
