पातञ्जल योगसूत्र (स्वामी विवेकानन्द भाष्य एवं सूत्र व्याख्या)

Patanjali Yoga Sutras
your ears there is a wave produced in your Chitta along with
it. So that wave represents 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-vibrations, 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 combined 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 practiced for a long time,
memory, the receptacle of all impressions, becomes purified,
and wwe are able clearly to distinguish them from one
another. This is called “Nirvitarka,” concentration without
reasoning.

By this process (the concentrations) with
discrim-ination and without discrimination, whose
objects are finer, are (also) explained.
