"Whatever states of mind, happy or unhappy, occur, never mind we should constantly be reminding ourselves, 'This is uncertain.'
"This is something people don't consider very much, that 'this is uncertain.' Just this is the vital factor that will bring about wisdom. In order to cease our coming and going and find rest, we only need to say, 'this is uncertain.' Sometimes we may be distraught over something to the point that tears are flowing; that is something not certain. When moods of desire or aversion come to us, we should just remind ourselves of this one thing. Whether standing, walking, sitting, or lying down, whatever appears is uncertain. Can't you do this? Keep it up no matter what happens. Give it a try. You don't need a lot just this will work. This is something that brings wisdom.”
