When we are physically and mentally calm, we have the ability to make choices in our lives. Often when we lose control we become physically or emotionally reactive. Not only does being aware of something as simple as breathing tell us a lot about the emotional state of ourselves and others, it gives us the chace to truly observe how and why we react in a certain way to specific circumstances. By anchoring in the present moment with our breath, the benefits of being in the moment are complimented by the natural relaxation that occurs with conscious breathing. Learning to be aware of our breathing is one of the single best tools we have for keeping a foothold in the present moment.
