The quest for internal peace and quiet has been the focus of many contemplative techniques, and yoga is certainly one of them. Most people associate yoga with physical postures and stretching to the point of contortion, but the physical practice we know today is actually pretty new (only about 100 years old). Traditionally, yoga has been about moving into stillness, and the postures were preparations for meditation.
One of the common misconceptions regarding meditation is that it is about "clearing the mind", but as long as we are alive our mind will produce thoughts- that is what the mind does. The practice is not about eliminating thoughts and feelings, but cultivating non-judgmental awareness. The Acoustic Ecologist Gordon Hempton defines silence not as an absence of sound, but an absence of noise. He's talking about natural sound, but he might as well have been referring to our mind.
Practicing non-judgmental awareness, whether it’s done formally through yoga and/or meditation or informally through present moment attention, can have a powerful positive effect on your health and wellbeing. This is primarily due to the fact that it stimulates the parasympathetic nervous system (the body's natural relaxation response), lowering the heart and breath rate, decreasing the secretion of stress hormones, and supporting healthy digestion. With practice meditation helps you dive into deeper realms of consciousness where there is simply an absence of noise, which is deeply nourishing for your whole-self.
Here is a great exercise to practice 'being' that can be done anywhere and anytime. Start by stopping. Still your body, either sitting or standing, close your eyes if that is comfortable to you, and shift your awareness to your senses. What is your body touching? What sounds do you hear? Are there any smells or tastes you can perceive? Then bring your attention to the feeling of your breath. Follow your breath where you feel it the most in your body, and let it flow freely. Breathe in, knowing that you are breathing in, breathe out, knowing that you are breathing out. Continue for a few minutes, and when you are ready to finish, deepen your breath and open your eyes if they are closed.
As an experiment, do this once a day for a week, and see what happens. You might gradually feel a visceral slowing down, even for just a moment. That is being.
