sighted people even, may have etheric vision. Though unable to read
the print in a book, they may be able to "see through a wall," owing to
the fact that their optic nerve responds more rapidly to fine than to
coarse vibrations.

When anyone views an object with etheric sight he sees _through_ that
object in a manner similar to the way an x-ray penetrates opaque
substances. If he looks at a sewing machine, he will perceive, first an
outer casing; then, the works within, and behind both, the casing furthest
away from him.

If he has developed the grade of spiritual vision which opens the Desire
World to him and he looks at the same object, he will see it both inside
and out. If he looks closely, he will perceive every little atom spinning
upon its axis and no part or particle will be excluded from his
perception.

But if his spiritual sight has been developed in such a measure that he is
capable of viewing the sewing machine with the vision peculiar to the
World of Thought, he will behold a cavity where he had previously seen the
form.

Things seen with etheric vision are very much alike in color, they are
nearly reddish-blue, purple or violet, according to the density of the
ether, but when we view any object with the spiritual sight pertaining to
the Desire World, it scintillates and coruscates in a thousand ever
changing colors so indescribably beautiful that they can only be compared
to living fire, and the writer therefore calls this grade of vision _color
sight_, but when the spiritual vision of the World of Thought is the
medium of perception, the seer finds that in addition to still more
beautiful colors, there issues from the cavity described a constant flow
of a certain harmonious _tone_. Thus this world wherein we now consciously
live and which we perceive by means of our physical senses is preeminently
the world of _form_, the Desire World is particularly the world of _color_
and the World of Thought is the realm of _tone_.

Because of the relative proximity or distance of these worlds, a statue, a
_form_, withstands the ravages of time for millenniums, but the _colors_
upon a painting fade in far shorter time, for they come from the Desire
World, and _music_ which is native to the World furthest removed from us,
the World of Thought, is like a will-o-the-wisp which none may catch or
hold, it is gone again as soon as it has made its appearance. But there is
in color and music a compensation for this incr
