Your meditation walk is to immerse yourself fully in the natural world while taking a (brief) sabbatical from the social world. This means, taking your cell phone with you but having it in the “silence all” answering mode – not vibrate, not beep, not low volume ringing – so that your phone’s silence mode maps to your silence mode.
On some of my walks, I use the ‘Holding the Silence’ step (see Mindful and Meditative Walking, step #3) to focus on the here and now through limited picture taking. During this stage, I hike with unfocused eyes and with the challenge to take three photos (no more, no less) of objects in my natural surrounding that tug at my attention – through their uniqueness or color or shape. For this, I typically use my cell phone camera – but calls in or out are still abide by the silence. More about the practice of “photo silences” in a future blog.
This is time for you, and you alone.
