"The more we are focused on outward awareness, the less time and energy we have to be focused on internal awareness.
Pratyahara is like taking all the millions of antennae all over our body and turning them from outward to inward. A total and complete withdrawal of all the senses, of all organs of perception.
It is important to realize that pratyahara is not a dulling of the senses. Rather it is simply turning the object of our senses from the external to the internal. Thus with the same keen awareness that we perceive the outside world, we are able to perceive the internal world."
~Swami Chidanand Saraswatiji
