rds on that scale, also.

To those to whom vibrations seem to be something merely connected with
sound-waves, etc., I would say that a general and hasty glance at some
elementary work on physical science will show that even the different
shades, hues and tints of the colors perceived by us arise from different
rates of vibrations. Color is nothing more than the result of certain
rates of vibrations of light recorded by our senses and interpreted by our
minds. From the low vibrations of red to the high vibrations of violet,
all the various colors of the spectrum have their own particular rate of
vibration. And, more than this, science knows that below the lowest red
vibrations, and above the highest violet vibrations, there are other
vibrations which our senses are unable to record, but which scientific
instruments register. The rays of light by which photographs are taken are
not perceived by the eye. There are a number of so-called chemical rays of
light which the eye does not perceive, but which may be caught by delicate
instruments. There is what science has called "dark light," which will
photograph in a room which appears pitch dark to the human sight.

Above the ordinary scale of light vibrations are the vibrations of the
X-Rays and other fine forces--these are not perceived by the eye, but are
caught by delicate instruments and recorded. Moreover, though science has
not as yet discovered the fact, occultists know that the vibrations of
mental and emotional states are just as true and regular as are those of
sound or light, or heat. Again, above the plane of the physical vibrations
arising from the brain and nervous system, there are the vibrations of the
astral counterparts of these, which are much higher in the scale. For even
the astral faculties and organs, while above the physical, still are under
the universal rule of vibration, and have their own rate thereof. The old
occult axiom: "As above, so below; as below, so above" is always seen to
work out on all planes of universal energy.

Closely following this idea of the universality of vibrations, and
intimately connected therewith, we have the principle of "induction,"
which is likewise universal, and found manifesting on all planes of
energy. "What is induction?" you may ask. Well, it is very simple, or very
complex--just as you may look at it. The principle of induction (on any
plane) is that inherent quality or attribute of energy by which the
manifestat
