The physical matter we know is just one aspect of matter.

"The physical matter we know is just one aspect of matter. It is

not true matter – even chemists and physicists do not know what

that is. When they start breaking matter down, they merely note

that energy is released. If their tools were more sophisticated,

they would in fact discover that this matter has given way to

another finer, subtler matter, belonging to another realm.

But humans will never succeed in breaking down ultimate matter:

only God can do that. When he breaks matter down, it will return

to his bosom; nothing will exist anymore, and there will be

absolute silence, a cosmic night. Until then, matter disappears

the way clouds disappear. You will have seen it happen: a few

white clouds begin to form out of a uniformly clear blue sky.

Where have they come from? And a few moments later, they have

faded into space and are no longer visible, although they are

there. It is really the density of matter that changes; matter

itself does not disappear, for it is the complementary pole to

spirit. Even splitting the atom does not make matter disappear."
