Exercise: During this week become aware of the trees around you. There are many aspects you can attend to, for example, their different shapes (round or slim, neat or shaggy in outline), different heights, ways of branching, and colors and types of foliage. Don't let the mind begin analyzing; just notice and appreciate trees. (If you live in a treeless area, you can change this to becoming aware of cacti, bushes, or grasses.)
A good time to notice trees is when you are driving or walking, or when you look out windows. If you have a chance, walk among the trees in a park, forest, or tree-lined street. Look at leaves and bark close up. Be aware that trees are breathing. What they breathe out (oxygen), we breathe in. What we breathe out (carbon dioxide), they breathe in.
OK. This is annoying. I wrote a fairly long post and it just disappeared. It was rambly and didn't make a lot of sense, but it was done... and now it's gone. I could tell you it was brilliant and insightful, but it wasn't. So I leave you with just this:
No. 1: The Larch. The... Larch
Oh. And there's nothing funny about trees. Nothing at all. Especially the Bansai... or the tall, hard, and mighty Sequoia. Nothing funny at all. So don't laugh.
