Concerning the operation of these vehicles: Motion, in our
Earth-world or any other, is the progressive change of a
material object in relation to its time and space. It is
here now, but it _was there_. Both space and time undergo a
simultaneous change; the object itself remains unaltered,
save in its _position_.

In the case of the vehicles, the current I have already
mentioned (used in the mechanism for the transition from
Earth to the other realm) that current, circulating in the
organic material of which the vehicle was composed, altered
the state of matter of the carrier and everything within the
aura of the current's field. The vehicle and all its
contents, with altered inherent vibratory rate of its
molecules, atoms and electrons, was in effect projected into
another world. A new dimension was added to it. It became an
imponderable wraith, resting dimly visible in a sort of
borderland upon the fringe of its own world.

Yet it had not changed _position_. It still remained
quiescent. Then the current was further altered, and the
time and space co-ordinates set into new combinations. This
change of the current was a _progressive_ change. Controlled
and carefully calculated by what intricate theoretic
principles and practical mechanisms no scientist of our
world can yet say.

It is clear, however, that as this progressive change in
space-time characteristics began, the vehicle perforce must
move slightly in space and time to reconcile itself to the
change.

There never has been a seemingly more abstruse subject for
the human mind to grasp than the theories involving a true
conception of space-time. Yet, doubtless, to those of Tako's
realm, inheriting, let me say, the consciousness of its
reality, there was nothing abstruse about it.

An analogy may make it clearer. The vehicle, hovering in the
borderland, might be called in a visible but gaseous state.
A solid can be turned to gas merely by the alteration of the
vibratory rate of its molecules.

This unmoving (gaseous) vehicle, is now further altered in
space-time characteristics. Suppose we say it is very
slightly thrown out of tune with its _spatial_ surroundings
at the time which is its _present_. Nature will allow no
such disorganization. The vehicle, as a sec
