The book isn't intended for general readers probably because the author _______ too many scientific terms(术语) in it.

In this modern world, we rush around all day, doing things, talking, sending and reading messages. We are always on, always connected, always thinking, always talking. There is no 36 for stillness.
And when we are 37 to be still because we’re in line for something, or waiting at a doctor’s appointment, or on a bus or train, we often  38 something to do. Some will play with mobile devices, other will read something. Being still isn’t something we’re 39.
This comes at a   40 : we lose that time for  41 , for observing and listening. We lose peace.
And   42 yet: sometimes too much action is worse than no action at all. You can run around crazily, but get  43 done.
Take a moment to think about  44 you spend your days. Are you constantly rushing around? Are you constantly reading and answering  45 checking on the news and the latest stream of information? Are you always  46 through your schedule?
Is this how you want to spend your  47 ? If so, peace be with you. If not, take a moment to be   48 . Don’t think about what you have to do, or what you’ve done already.   49 be in the moment.
Then after a minute or two of doing that, consider your life, and how you’d  50 it to be. See your life with less move anent, less doing, less rushing. See it with more stillness, more consideration, more  51 .
Then be that vision.
It’s pretty simple: all you have to do is sit still for a little bit each day.   52 you’re gotten used to that, try doing less each day. Breathe when you feel yourself moving too  53 . slow down. Be present. Find happiness now, in this moment, instead of   54 for it.
