then no action from outside. The sensory motions,
therefore, are coiled up somewhere, just as the motor
motions are known to be in different centres. For
instance, I see a city; the perception of that city was
from the reaction to the sensations brought from out
side objects comprising that city. That is to say, a
certain motion in the brain
molecules has been set up
by the motion in the incarrying nerves, which again
were set in motion by external objects in the city.
Now, even after a long time I can remember the city.
This memory is exactly the same phenomenon, only it
is in a milder form. But whence is the action that set
up even the milder form of similar vibrations in the
brain. Not certainly from the primary sensations.
Therefore it must be that the sensations are coiled up
somewhere, and they, by their acting, bring out the
mild reaction which we call dream perception. Now
the centre where all these residual sensations are, as it
were, stored up, is called the MAlddhdra, the root recep
tacle, and the coiled up energy of action is Kundalini,
the coiled up."
It is
very probable that the residual
motor energy
is also stored up in the same centre as,
after deep study or meditation on external objects, the
part of the body where the Mfilddhdra centre is situ
ated (probably the sacral plexus) gets heated. Now,
if this coiled-up energy be roused and made active, and
then consciously made to travel up the SuSumnd canal,
as it acts upon centre after centre, a tremendous reac
tion will set in. When a minute portion of the energy
of action travels along a nerve fibre and causes reaction
