Yoga stimulates different nerves in your body, especially the Vagus nerve that carries information from the brain to most of the body's major organs, slows everything down and allows self-regulation. It's the nerve that is associated with the parasympathetic system and emotions like love, joy and compassion.
Deepak ChopraSelf-awareness is your awareness of the world, which you experience through the five senses (sound, touch, sight, taste, and smell). Pay attention to your sensory impressions and be aware of those five ways that the world comes to you.
