If you can't sleep or wake up in the middle of the night and cannot get back to sleep within 15-20 minutes, don't lie there worrying about it.

如果你无法入睡或醒来在半夜起来，不能回去睡觉15 - 20分钟内，不在于有必要担心。

Meditation, live sleep, cannot be taught-it comes by itself, in its own time.

冥想，就像睡眠，不能教，它是自发的。

Don't believe that you can always "catch some sleep or rest later." Your body cannot make up for lost sleep or rest time because it is not physiologically possible.

不要相信你总能“在以后能补上睡眠和休息”，你的身体不能对失去的睡眠和休息有所补偿，因为从生理学角度来讲这是不可能的。
