One of my favorite meditations is when I imagine my self high in a corner of the room observing myself meditating. This allows me to become “self-aware” to observe how my body and mind are working. I’ve taken this technique to the road and sometimes to the treadmill. It allows me to be aware of my mechanics, breathing, stride but most importantly me “The Observer”.
Some of the things I focus on other than my actual running are the things in my environment. Bird song, scents, colors, temperature changes. Using all my senses creates a greater sense of Joy with the run, it no longer is a physical exercise but a metaphysical exercise.
Try Observing yourself even for five minutes, you may discover something wonderful!
