While you are in an asana practice, listen to your breath and tune into your mantra. What sound do you hear while breathing? Does it feel good? Focus on it. Breathe and BE with it. This is yoga. This is union of the senses. This is union of mind and body.
Breathe and notice the subtle shifts. Feel your prana or chi flow through each movement. Be with each moment and each breath.
Subtle shifts occur when we withdraw the senses and feel the power of mountain pose. Feel your root as you ground into the earth. As you flow through the asana or move with the breath, begin to meditate on your mantra. Begin to trance out into a sound zone that flows with your life force. Make your breath and mantra one.
Take this practice and live your life fully. I promise you will like it.
