Incredible as this seems to our ordinary ideas, it is undoubtedly an
understatement rather than an exaggeration of the true proportion as
observed in the case of koilon. We shall understand how this can be so if
we remember that koilon seems absolutely homogeneous and solid even when
examined by a power of magnification which makes physical atoms appear in
size and arrangement like cottages scattered over a lonely moor, and when
we further add to this the recollection that the bubbles of which these
atoms in turn are composed are themselves what may be not inaptly called
fragments of nothingness.

In the same pamphlet Sir Oliver Lodge makes a very striking estimate of the
intrinsic energy of the æther. He says: "The total output of a
million-kilowatt power station for thirty million years exists permanently,
and at present inaccessibly in every cubic millimetre of space." Here again
he is probably underestimating the stupendous truth.

It may naturally be asked how, if all this be so, it is possible that we
can move about freely in a solid ten thousand million times denser, as Sir
Oliver Lodge says, than platinum. The obvious answer is that, where
densities differ sufficiently, they can move through each other with
perfect freedom; water or air can pass through cloth; air can pass through
water; an astral form passes unconsciously through a physical wall, or
through an ordinary human body; many of us have seen an astral form walk
through a physical, neither being conscious of the passage; it does not
matter whether we say that a ghost has passed through a wall, or a wall has
passed through a ghost. A gnome passes freely through a rock, and walks
about within the earth, as comfortably as we walk about in the air. A
deeper answer is that consciousness can recognize only consciousness, that
since we are of the nature of the LOGOS we can sense only those things
which are also of His nature. These bubbles are His essence, His life, and,
