“Make the mind mindful and keep it aware all the time. The problem is how to keep it aware. Suppose you have an area about three meters wide and you’re sitting inside it. And there’s a big cobra staying in there, too. What would your mind be like then? Because you don’t trust the cobra, because it’s poisonous, you won’t dare lie down. You won’t dare get drowsy. Why? Because you’re afraid of the cobra. When you understand in this way, your awareness will get a lot clearer.”
