YOGA APHORISMS. 14!
what these three are. Here is the Chitta ; you will
always remember the simile of the lake, the mindstuff,
and the vibration, the word, the sound, like a
pulsation coming over it. You have that calm lake
in you, and I pronounce a word,
"cow." As soon as
it enters through your ears there is a wave produced
in your Chitta along with it. So that wave repre
sents the idea of the cow, the form or the meaning
as we call it. That apparent cow that you know is
really that wave in the mind-stuff, and that comes as
a reaction to the internal and external sound vibra
tions, and with the sound, the wave dies away; that
wave can never exist without a word. You may ask
how it is when we only think of the cow, and do not
hear a sound. You make that sound yourself. You
are saying
"cow"
faintly in your mind, and with that
comes a wave. There cannot be any wave without
this impulse of sound, and when it is not from outside
it is from inside, and when the sound dies, the wave
dies. What remains? The result of the reaction, and
that is
knowledge. These three are so closely com
bined in our mind that we cannot separate them. When
the sound comes, the senses vibrate, and the wave
rises in reaction; they follow so closely upon one
another that there is no discerning one from the other;
when this meditation has been practised for a long
time, memory, the receptacle of all impressions,
becomes purified, and we are able clearly to distinguish
them from one another. This is called
concentration without reasoning.
