ce. A thought-form is really but a strongly manifested thought or
feeling which has taken form in the astral substance. Its power and
duration depend upon the degree of force of the thought or feeling
manifesting it.

These thought-forms differ very materially from one another in form and
general appearance. The most common form is that of a tiny series of
waves, similar to those caused by the dropping of a pebble in a pond of
water. Sometimes the thought-form takes on the appearance of a whirlpool,
rotating around a centre, and moving through space as well. Another form
is like that of the pin-wheel fireworks, swirling away from its centre as
it moves through space. Still another form is that of a whirling ring,
like that emitted from a smokestack of a locomotive, or the mouth of a
smoker--the familiar "ring" of the smoker. Others have the form and
appearance of semi-luminous globes, glowing like a giant opal.

Other thought-forms are emitted in jet-like streams, like steam puffed out
from a tea-kettle. Again, it will appear as a series of short puffs of
steam-like appearance. Again, it will twist along like an eel or snake.
Another time it will twist its way like a corkscrew. At other times it
will appear as a bomb, or series of bombs projected from the aura of the
thinker. Sometimes, as in the case of a vigorous thinker or speaker, these
thought-form bombs will be seen to explode when they reach the aura of the
person addressed or thought of. Other forms appear like nebulous things
resembling an octopus, whose twining tentacles twist around the person to
whom they are directed.

Each thought-form bears the same color that it possessed when generated in
the aura of its creator, though the colors seem to fade with time. Many of
them glow with a dull phosphorescence, instead of bright coloring. The
atmosphere of every person, and every place, is filled with various
thought-forms emanated from the person, or persons who inhabit the place.
Each building has its own distinctive thought-forms, which permeate its
mental atmosphere, and which are clearly discernible by trained
clairvoyant vision.

I here take the liberty of quoting a few paragraphs from my little book
entitled "The Astral World," in which the phenomena of the astral plane
are explained in detail. I reproduce them here in order to show you what
you may see on the astral plane when your clairvoyant vision is
sufficiently developed to function there. The word
