The center of the universe and peace at last

As I see it, the mind is like a single point, the center of the universe, and mental states are like visitors who come to stay at this point for short or long periods of time. Get to know these visitors well. Become familiar with the vivid pictures they paint, the alluring stories they tell, to entice you to follow them. But do not give up your seat - it is the only chair around. If you continue to occupy it unceasingly, greeting each guest as it comes, firmly establishing yourself in awareness, transforming your mind into the one who knows, the one who is awake, the visitors will eventually stop coming back. If you give them real attention, how many time can these visitors return? Speak with them here, and you will know every one of them well. Then your mind will at last be at peace.

Ajahn Chah, in A Still Forest Pool, quoted from Jack Kornfield, The Buddha is Still Teaching, 131.
