正确答案：A window likewise allows those who are inside to see outside and also allows outsiders to see inside. That is why those who live in bustling areas need to draw their curtains to protect their privacy. When visiting friends at night there's no need to wait until the door is opened to ask if they're there — you can tell that by the light inside the window. Similarly you don't need to wait for a man to open his mouth to work out what's on his mind — you can see that from his eyes. Shutting a window works in the same way as closing one's eyes.

If outside there is too much noise and excitement closing the window will make it easier for the soul to engage in free exploration and quiet contemplation.
