Just like the question “Can you see your own eyes?” Nobody can see their own eyes. I can see your eyes but I can’t see my eyes. I’m sitting right here, I’ve got two eyes and I can’t see them. But you can see my eyes. But there’s no need for me to see my eyes because I can see! It’s ridiculous, isn’t it? If I started saying “Why can’t I see my own eyes?” you’d think “Ajahn Sumedho’s really weird, isn’t he!” Looking in a mirror you can see a reflection, but that’s not your eyes, it’s a reflection of your eyes. There’s no way that I’ve been able to look and see my own eyes, but then it’s not necessary to see your own eyes. It’s not necessary to know who it is that knows — because there’s knowing.
