Changing ourselves is changing the world and changing the world is changing ourselves. That constantly flowing activity, like imagining infinity, is practically impossible for the frontal lobe to frame. I did meet this simple truism again on Sunday though. After a filthy, crushing week of work I'd been hawked-out onto Saturday, indolent and irritable. After a day behind the sofa I dragged the unforgiving carcass into the garden on Sunday and weeded, chopped, pruned, dug and mowed my way to a more balanced me, and hey presto, a more balanced garden. Doing what needs to be done changes us and changes the world.
