I think being silent means not to think anything, you know? Like in meditation, you try to quiet your mind kind of.
Edit. But of course, if you find it extremely hard to do while meditating, maybe you try it too much. Just let go. And when you notice your thinking about something, just accept it and return to the "silent mode". That's how I do it.
