Walking meditation is a slow, contemplative walking practice or exercise in which I mindfully observe myself lifting my feet one at a time and then placing each one down again.
Paying attention to everything with concsciously heightened awareness: the sights, sounds, smells, the feel of my body moving ahead along the path, the feel of my feet on the earth with each step.
And when I find my attention wandering, I stop walking and stand still, gently collecting myself and recollecting what I was engaged in, also the moments when I make photos. I take a few deep breaths, and then start moving ahead again.
