The comments on the first post have been helpful and have lead me to a modus operandi for my morning walks, if not an answer. Today's ice, atop the crusted snow after yesterday's rain, made it even more dangerous to stray off the snowmobile tracks. I had to concentrate on each step in front of me as I felt my way across the field. At one point, skirting a stream, I broke through snow up to my knee.
But it all served to keep me in the present. That's good, and the essence of the kind of Buddhist meditation I've been taught. I used to meditate sitting crosslegged in a "zendo" or meditation-room, at the home of a Buddhist monk who led group meditations three mornings a week. We're lucky in where we live, because this guy is right down the road from us. The group of us would simply sit and listen to our breaths, focusing on them to quiet the mind and keep it from roaming to endless reruns of the past or plans for the future that seem to dominate my mind, at least. There was no conflict with visual imagination then, when images would float into my mind. As long as I zeroed in on them, they would take the place of my breath, forming a new present that changed color and shape behind my eyelids as I watched. It seemed that I was sustaining the meditative focus, keeping my mind free of the coming day's to-do list or yesterday's regrets.
When we got our new dog, though, about a year and a half ago, I had to stop going to the group meditation, to help my husband train our dog on early morning walks. Now Cody's trained well enough for us to simply walk as "a pack," but I'm too attached to our walks to go back to the zendo for meditation. So I'm trying to make the walks serve as my meditation time. I pick out a tree or telephone pole about a hundred yards up the road, and try to focus on the rise and fall of my breath, or the sound or feel of my steps, until I reach the marker. Then I pick out a new one, and do the same thing. The ideal, of course, is to extend the focus on the breath or other sensations to cover the whole course of the hour's walk.
Needless to say, I can't sustain my focus that long. Too often, the marker up ahead snaps me out of some reverie, which usually involves the immediate future: what I need to xerox for class, what I need to buy for dinner, etc. If it involved more imaginative flights, such as Terri describes, above, or Notdotdot's "useful ideas" that I could use in some creative way - say in a scene in my writing - it would be wonderful. But mostly I'm lost in the mundane worries about what I have to do, what I didn't get done yesterday, and looking forward to the weekend.
However, the rare moments I can stay in the present are worth the long waits. Feeling one's attention rise and fall on the breath causes a vacuum in the mind that sucks in whatever is there: wind, the smell of snow or rain in the air, crunch of ice under your feet, muscles contracting in your lower back as you walk, or white flag of tail sashaying back and forth over Cody's hindquarters as he trots ahead. This awareness often triggers a slight feeling of alarm over the loss of the familiar: those old tapes anchoring me to the past and a sense of who I am over a continuum. When the here and now comes rushing in, I could be anyone or thing: a hot-air balloon loosed from its ropes and sandbags, rising into thinning air.
So what I've learned from this walking meditation is that it seems to work when you concentrate on your breath, the sound of your footsteps, the marker you've picked out down the road - the here and now of your surroundings. When you stray from the concrete sense impressions of the present, and start seeing yourself in the grocery aisle as you pick up tonight's dinner, nothing happens. You might as well be doing errands. So being taken from the present surroundings by flights of fancy, imagination, doesn't work in walking meditation (unlike sitting meditation).
However, since looking over the comments above, it seems like imagination and meditation might be more compatible than they first seem. Done intentionally at different times, one might help the other. Focusing on the breath on the morning walk can quiet the mind if it's sustained over a hundred yards or so (to the next marker); this slowing of the mind can extend into one's day, and might make room for visions of how to do things better. I've often noticed that the hours after the morning walk feel better, run more smoothly, and that one's body feels lighter, more buoyant, as it moves through the day. I feel simultaneously relaxed and energized as I teach or write. And so I'm going to choose to believe, over the next year, that walking meditation nurtures imagination.
Yesterday, my husband and I went to our favorite beach to run our daughter's and our dogs. It happened to be low tide, uncovering a sandbar out to a distant island of long, low black rocks. As we started out towards the island, the sand's hard ridged strands sided by low, waterlogged soft spots, exacted close attention to our footing. My mind had the wonderful emptiness that sucked in the play of a crisp breeze in my hair, the crash of waves in my ears.
And then I heard my husband's call over the waves. He was up ahead, turned toward me and pointing to the island. There, cantering against the black rocks, was a white horse, with a black-clothed rider. The horse's neck was arched, streaming white feathers of mane and tail back in the wind.
It was like the reward of a vision for my effort of concentration on the sand moments before. But it wasn't my imagination; it was real.
