Every tree has a spark of life. Often these are non-sapient souls, but they're sufficiently lively nonetheless. The same goes for other plants. The people-trees are said to be in a state of constant or near-constant meditation. A forest is basically a massive number of hardcore meditating monks.
We emerged from the forest road and were now driving by a suburb. I thought about the landscaping and gardening.
Landscaping and gardening are the arts of picking up mostly-oblivious meditating monks, and rearranging them in more visually pleasing ways.
