Someone from one of the email lists I'm on wrote, "Higher learning is perhaps sitting high in a tree and watching."
Yesterday, I sat listening to music and staring into space for several hours. It reminded me that when I was growing up, I often spent time like that. Nowadays, I tend to keep myself occupied at all times. If I'm just sitting still, I read or watch TV. But when I have those times of just letting my thoughts wander, I find I have more inner peace.
