and Thought-Waves of greater or lesser intensity. This force once set
into motion persists, for a greater or lesser period of time, in
Ether. Thought-Force is the concentration of a high form of vibratory
energy in the Akasa (universal ether) and the ether, as you know,
permeates all space, interpenetrates and pervades all forms of matter,
from atom to the sun and the stars. Just as the light-waves of a star
exist and move on centuries after the star has ceased to be, just as the
heat-vibrations remain in a room even after the producing cause has been
removed, similarly mentative energy and its corresponding Thought-Forms
persist in the ether even after the originating impulse has been
withdrawn.

_(c) Thought-Atmosphere._

In this way places, houses, cities and temples have peculiar
Thought-Atmospheres of their own, imparted by those living there,
exerting an influence upon every one living or going there. These are
positive, animating, purifying and exalting Thought-Atmospheres, and
there are negative, weakening and unholy, morbid Thought-Atmospheres.

The higher and loftier your tone of general Thought-Activity, the
finer and more powerful the vibrational nature of the energy emanating
from you. The quality of the thought determines the rate of vibration.
For instance, photographs have been taken through highly-sensitized
plates, indicating the nature of the energy generated. Tongues of flame,
brilliant and flashing with golden-yellow, were photographed from prayer
and devotion. Rotary forms spreading out in ever widening circles of
intense power appeared from lofty enthusiasm in a noble cause. Dark,
murky, cloudy forms resulted from fear, morbidness and worry, and so on.
