Space and Time
When I was younger I went through a pretty serious Zen period. What I mean is, I put real effort into sitting meditation. I spent plenty of time on a zafu in front of a white wall. These days, I have a different approach, easier on the old piriformis. Plus, it ties into my art practice a little more directly, I think. I try to bring my visual attention to a state of focus so that I can notice things. I enjoy this practice and once in a while get a photo that is meaningful to me.
