Nothing is so beautiful as spring - when weeds, in wheels, shoot long and lovely and lush; Thrush's eggs look little low heavens, and thrush through the echoing timber does so rinse and wring the ear, it strikes like lightning to hear him sing.

The sound of your laughter is still echoing in the room of my memories. - F.M. Sogamiah

Peace is white sun reflections on summer pear trees, and ocean mist droplets defying gravity by air currents. Peace is caffeinated goodbye-kissing and velvet smiles laced with credence. Trumpet horns sound off the coming of Blue Jays, Swallows and Chickadee's. And there is no sadness echoing within or without. There is a taste of God in every grass blade and car horn raging in the city. The stop lights are all green, and there are children playing in the fountains. A dog laps my hand, and finally-I remembered what it's all about.

Walking causes a repetitive, spontaneous poetry to rise naturally to the lips, words as simple as the sound of footsteps on the road. There also seems to be an echo of walking in the practice of two choruses singing a psalm in alternate verses, each on a single note, a practice that makes it possible to chant and listen by turns. Its main effect is one of repetition and alternation that St Ambrose compared to the sound of the sea: when a gentle surf is breaking quietly on the shore the regularity of the sound doesn't break the silence, but structures it and renders it audible. Psalmody in the same way, in the to-and-fro of alternating responses, produces (Ambrose said) a happy tranquillity in the soul. The echoing chants, the ebb and flow of waves recall the alternating movement of walking legs: not to shatter but to make the world's presence palpable and keep time with it. And just as Claudel said that sound renders silence accessible and useful, it ought to be said that walking renders presence accessible and useful.

He walked on in silence, the solitary sound of his footsteps echoing in his head, as in a deserted street, at dawn. His solitude was so complete, beneath a lovely sky as mellow and serene as a good conscience, amid that busy throng, that he was amazed at his own existence; he must be somebody else's nightmare, and whoever it was would certainly awaken soon.

This was supposed to be yesterday. I was sitting on the Cardiff/London train, supposedly about to write this very column, and realising something quite terrible. My head was entirely empty. A vast echoing void. Bigger on the inside, but with nothing in it. You could drop a pebble in my brain and wait for an hour to hear it land. No actually, you couldn't - that would be aggressive and unhelpful, so keep your damn pebbles to yourself.

Nothing is so beautiful as spring - when weeds in wheels shoot long and lovely and lush Thrush's eggs look little low heavens and thrush through the echoing timber does so rinse and wring the ear it strikes like lightning to hear him sing.
