Pratyahara is the refinement of our Five senses. There is much we can do to awaken our mind through our senses. But the most active of all practices? To shift our mind into a new space... is to reduce the barage of information and excitement coming to us through the day via our senses.
Quieting the mind involves reducing our involvement in the modern world experiential way of life, and making time to just sit and wait.
Our senses our what the world meets first, so it is the senses which need to be retrained to seek less and to be content with what comes to them, rather than grasping for more.
Just for a moment, Sit and breathe. See where your skin feels the moment, what sounds come to your ears, what taste is now in your mouth, added to the smell in our nose, and what meets your eyes at this moment. And breathe and wait.
